3. Installation

Before upgrading

If you are upgrading from an earlier version of Mathcad to Mathcad 7, make sure you still have the earlier version of Mathcad installed on your system. The upgrade installation must locate the earlier version before it will install Mathcad 7, and it will install Mathcad 7 over the earlier version by default. You may choose another location during the installation. If you have Mathcad Electronic Books or Function Packs, please see Using Electronic Books in Mathcad 7, below.

Note to beta testers

If you installed a beta version of Mathcad 7, you should first uninstall the beta version before installing Mathcad 7. To uninstall Mathcad 7 in Windows 95 or Windows NT 4.0:

0. From the Start menu, choose Settings=>Control Panel=>Add/Remove Programs.

1. Select Mathcad 7 from the list of programs.

2. Click Add/Remove.

To uninstall the beta version of Mathcad 7 under Windows NT 3.51, double-click on the Uninstall icon in the MathSoft group.

General installation instructions

To install Mathcad 7 Professional:

0. Insert the CD into your CD-ROM drive. The first time you do this, the CD will automatically start the installation program under Windows 95 and NT 4.0.

1. If you are using Windows NT 3.51 or if the installation program does not run automatically, you can start it by choosing Run from Start menu (under Windows 95 or higher) and type D:\SETUP (where "D:" is your CD-ROM drive). Click OK.

2. When prompted, enter your product serial number, which is located on the inside cover of your Mathcad User's Guide.

3. Follow the remaining on-screen instructions.

If you are installing Mathcad from diskettes, run SETUP.EXE on the first installation diskette.

Typical vs. custom installation

The custom installation gives you the option of installing the following:

0. Mathcad Professional Program Files: all the files necessary to run Mathcad and MathConnex and its on-line Help, patch Axum 5 to work with Mathcad 7, as well as run Microsoft Internet Explorer (Internet Explorer installation from CD only).

1. Resource Center Files: reference files consisting of a tutorial, reference tables, and in-depth guides to solving, statistics, and programming in Mathcad. If you choose not to install the Resource Center files, you must have the CD available when you choose Resource Center from the Mathcad Help menu in order to access the Resource Center contents.

2. Sample EFI Files: examples of files you can use to create a user DLL for Mathcad using C or C++.

The typical installation (the default) installs all of the Mathcad and MathConnex program files, the Resource Center files, and sample EFI files. The typical installation requires approximately 55 megabytes. A minimal installation of Mathcad Professional Program Files only requires approximately 18 megabytes.

Axum patch

During the Mathcad 7 installation, the installation program will detect whether you have Axum 5 installed on your system. If you do, a message appears asking whether you want to update your copy of Axum 5 to the latest version (dated 5/18/97). You need to update Axum 5 to this version in order to use the Mathcad–Axum link, which allows you to create Axum graphs in a Mathcad 7 worksheet or in a MathConnex project. See the Troubleshooting section below for more information on the Mathcad–Axum link.

Microsoft Internet Explorer

To browse the World Wide Web through the Mathcad Resource Center, you need to install Microsoft Internet Explorer 3.02 or higher. The Mathcad installation program on CD will detect whether you have Internet Explorer 3.02 or higher; if you do not, you will have the option of installing Microsoft Internet Explorer from the Installation CD. If you are installing Mathcad from diskettes instead and wish to browse Web files from within Mathcad, download the latest Microsoft Internet Explorer from http://www.microsoft.com/ie.

If you browse to a web page containing a Java applet while browsing the Web using the Resource Center, Mathcad could cause an illegal application error because of a problem in the current version of Microsoft's Java virtual machine. To prevent this, we recommend that you either disable Java programs in your copy of Internet Explorer, or refrain from browsing the Web through the Resource Center until this problem is corrected. See the Troubleshooting section below for more information.

4. Updates to Documentation

The following are corrections to the printed documentation for Mathcad and MathConnex. Consult the on-line Help in Mathcad and MathConnex as well as the Adobe Acrobat files provided in the DOC folder on your installation CD for the most recent documentation on Mathcad and MathConnex. See README.RTF in the DOC folder for more information on using the Adobe Acrobat files.

Mathcad User's Guide

0. Web browsing in the Resource Center is supported under Windows 95 and Windows NT 4.0 but not Windows NT 3.51 (p. 39). Under Windows NT 3.51, Microsoft Internet Explorer is launched when you attempt to access files on the Web from within the Resource Center.

1. To toggle out of context-sensitive Help, use [Shift][F1] instead of [Esc] (p. 46)

2. Using the [Ctrl] and [Shift] keys to copy and move math expressions by dragging is not supported (p. 63).

3. When you save a Mathcad 7 worksheet as a Mathcad 6 worksheet, regions or features that won't work in Mathcad 6 are saved as bitmaps (p. 78).

4. Borders are not supported as either a general text region property (p. 114) or equation property (p. 129). A border may, however, be placed on a picture region (p. 591).

5. To apply a background highlight color to either a text region (p. 115) or equation (p. 129), click on the region, choose Properties from the Format menu, click on the Display tab, and click on the "Highlight Region" checkbox. The description of background highlight color for text regions should refer to text regions, not equations (p. 115).

6. Individual equations in Mathcad worksheets can only be disabled, not locked (p. 150). To lock one or more regions in your Mathcad worksheet, set a "lock area" as described on pp. 85–88.

7. When you apply a keyword to the result of another, the result will temporarily disappear while you enter the keyword in the placeholder. When you press [Enter] you will see the new result and the previous one (p.359).

8. Pasting Excel data from the clipboard into a placeholder in a Mathcad worksheet creates a Mathcad matrix, not an Excel component (p. 431).

9. Dragging and dropping data from another application into Mathcad always creates an embedded object, provided that the originating application supports OLE. You cannot drag and drop data into a Mathcad placeholder (p. 432).

10. The versions of VBScript and JScript installed with the version of Microsoft Internet Explorer (v. 3.02) provided with Mathcad should not be used to script the Scriptable Object component (p. 447). You must download current versions of VBScript and JScript from http://www.microsoft.com/vbscript and http://www.microsoft.com/jscript.

11. READ_HLS(file) creates a matrix in which the color information in file is represented by values of hue, lightness, and saturation; READ_HSV(file) creates a matrix in which the color information in file is represented by values of hue, saturation, and value (p. 588).

12. The activity unit Bq is available in all systems of units (p. 638).

MathConnex Getting Started Guide

0. MathConnex chooses a default icon when you display a component as an icon (p. 36). To change the icon, click on the component, choose Object=>Convert from the Edit menu, click the "Display as Icon" checkbox, and click "Change Icon." Select a different icon from the available choices.

1. When used to export data to an external file, the File Read/Write component automatically overwrites the file whenever the component computes. To receive a warning that the file will be overwritten, click once on the component with the right mouse button and choose Overwrite File from the context menu so that it is no longer checked (pp. 46–47).

2. The Scripted Object component has additional methods and properties not described on p. 76: The IsComplex property returns "TRUE" if a DataValue has a valid imaginary part, and "FALSE" otherwise. The errmsg function takes a string parameter as argument that is displayed as an error message within the script and causes the script to stop execution. Go to http://www.mathsoft.com/mcadlib/mathconnex/ on the Web for more documentation on using the Scripted Object component.

3. Additional built-in functions in ConnexScript include trunc (remove trailing decimals), round (round to nearest integer), and mod (integer remainder after division) (p. 79). See the on-line Help in MathConnex for more on ConnexScript.

5. Using Electronic Books In Mathcad 7

Mathcad Electronic Books created for earlier versions of Mathcad operate correctly in Mathcad 7. Note, however, the following differences:

0. Open an Electronic Book by choosing Open from the File menu and locating the corresponding HBK file for the Book, or choose Open Book from the Help menu. Titles for Electronic Books you have installed in the HANDBOOK folder of your Mathcad installation directory will appear at the bottom of the Help menu, and you can open an Electronic Book by selecting directly from this list. If you are upgrading from an earlier version of Mathcad and installing Mathcad 7 in a new location, be sure to copy your current HANDBOOK folder to the new location to have easy access to your Electronic Books.

1. All Electronic Books open inside a small, custom window with an Electronic Book toolbar like the one for the Mathcad 7 Resource Center. You may open as many Electronic Books as you like at any time, each in its own window. The window is easily resized for optimal viewing of the Electronic Book.

2. The Electronic Book navigational controls differ from their earlier counterparts. You now can access the Table of Contents (house icon), the previous or next topic in the Electronic Book content order (blue arrows), or the previous or next topic in the actual sequence of visited topics (yellow arrows). The navigational controls also include: a history list, a search button, and buttons for copying, printing, and saving the Electronic Book.

3. The "paste region" and "paste file" region actions are no longer supported. This change affects The CRC Materials Science and Engineering Handbook and The CRC Handbook of Chemistry and Physics. Note that you may now easily copy material from the Electronic Book directly to your Mathcad worksheet by dragging and dropping.

4. Commands for annotating the Electronic Book are available on a context menu that appears when you click on a blank area of the Electronic Book with the right mouse button.

5. File access functions in the Image Processing Function Pack require string variable arguments in Mathcad 7. See the section "Arguments to file access functions" in the Mathcad User's Guide for more information.

6. The Mathcad–Apollonius DDE links in Parametric Sketching for Engineering Analysis with Mathcad and Apollonius are not supported.

7. If you own the Image Processing Function Pack, you must first patch your function DLL files for the functions to operate correctly in Mathcad 7. Patch files and instructions are provided in the \FPACK folder on the CD. Refer to the MathSoft Web site (www.mathsoft.com) for the lastest information regarding other function packs.

6. A Note about Components

Mathcad 7 Professional and MathConnex both use "components" to communicate and exchange data with the applications Axum, Excel, and MATLAB, as well as external data sources. Components are specialized OLE objects that not only link to external data sources and applications but also allow you to compute with these sources or applications within your Mathcad or MathConnex worksheet.

Common components in Mathcad and MathConnex

The components available in Mathcad 7 Professional (Input Table, Output Table, Axum, Excel, MATLAB, Scriptable Object) are essentially identical to their counterparts in MathConnex, although they display differently in the two applications:

0. For most components a Wizard guides you through initial configuration of the input and output variables (Mathcad) or ports (MathConnex).

1. You double-click the component to activate it for editing.

2. You click once on the component with the right mouse button to access a context menu.

3. The Properties selection on the context menu allows you to edit most of the configuration options.

Using the Axum, Excel, and MATLAB components

To use the Axum, Excel, or MATLAB component in either Mathcad or MathConnex:

0. You must have a supported version of the corresponding application on your system: Axum 5 (dated 5/18/97) or later, Excel for Windows 95 or later, and MATLAB Professional 4.2c (MATLAB 5 is not currently supported). If you already have Axum 5 installed on your system, the Mathcad installation program allows you to patch your copy of Axum to work with Mathcad 7 and MathConnex.

1. You must have sufficient memory on your system to run both Mathcad (or MathConnex) and the other application(s). In practice, we recommend a minimum of 32 megabytes of RAM.

2. Worksheets that include components can be shared with others; however, the components will not compute unless the person receiving the worksheet has all the necessary applications installed on his or her system.

7. Menu changes from Mathcad 6

If you're upgrading to Mathcad 7 from Mathcad 6, you'll notice that we've reorganized the menu commands to make them more intuitive. The View, Insert, and Format menus are new, and the Text and Graphics menus have been removed. Some other specific changes include:

0. File/Export Worksheet has been removed; you may now save a Mathcad worksheet in RTF format using the File/Save As command.

1. File/Open URL has been moved to the Collaboratory dialog box. Access the Collaboratory with File/Collaboratory and use the URL text box at the bottom of the dialog box.

2. File/Insert has been renamed Insert/Worksheet.

3. The File/Get From Notes and File/Save to Notes commands have been removed. This functionality is no longer available.

4. File/Save Configuration and File/Execute Configuration have been removed. You can now save preferred worksheet settings by creating a template.

0. Edit/Redo has been added to let you reapply an edit undone by Edit/Undo.

1. Edit/Delete replaces Edit/Clear.

2. Edit/Regions/View Regions is now a command on the View menu.

3. Edit/Regions/Select All, Edit/Regions/Separate, Edit/Regions/Align Regions, Edit/Regions/Lock Regions, and Edit/Headers/Footers have been moved to the Format menu.

4. Edit/Insert Pagebreak and Edit/Link have been moved to the Insert menu.

5. Edit/Include has been renamed Insert/Reference.

6. Edit/Insert (Delete) Blank Lines has been removed. Insert or delete blank lines by clicking in the worksheet and pressing the [Enter], [Backspace], or [Delete] key.

0. The Text menu has been deleted and the available commands have been distributed among other menus. Insert a text region into your worksheet as before using the double-quote key " or choose Insert/Text Region. The Text/Create Text Paragraph command is no longer available; only text regions can now be created. Text/Embed Math has been moved to Insert/Math Region. Text/Change Font and Text/Change Paragraph Format have been moved to the Format menu. Text/Check Spelling has been moved to the Edit menu.

0. The Math/Matrices, Math/Choose Function, and Math/Units/Insert Unit commands have been moved to the Insert menu.

1. The Math/Units/Change System of Units, Math/Units/Dimensional Format, Math/Randomize, and Math/Built-in Variables commands have been reorganized under the Math/Options pick.

2. Math/Numerical Format, Math/Font Tag and Math/Highlight Equation have been moved to the Format menu.

3. Math/Change to Greek Variable is no longer available. Change a character behind the insertion point in math regions to Greek by pressing [Ctrl]G.

0. The Graphics menu has been deleted and the available commands have been distributed among other menus. Use the Insert/Graph pick to insert available built-in two- and three-dimensional plot operators, and use the Insert/Picture command to insert a picture operator. Format a selected plot or picture by using the Format/Graph or Format/Picture command, or by double-clicking on the plot or picture. For X-Y and Polar Plots, Trace and Zoom are available as commands on Format/Graph as well as buttons on the Graphing Palette.

0. The available Symbolics menu commands are identical to those in Mathcad PLUS 6.0 but have been renamed or reordered for clarity. The Differentiate on Variable, Integrate on Variable, Solve for Variable, and Substitute for Variable commands have been grouped under the Symbolics/Variable command. Symbolics/Derivation Format has been renamed Symbolic/Evaluation Style and Symbolics/Derive in Place is now part of the Evaluation Style dialog box.

0. Most worksheet management commands formerly on the Window menu have been moved to the View, Insert, and Format menus. Window/Zoom, Window/Refresh, and the palette and toolbar hiding and viewing commands have been moved to the View menu. The Window/Animation commands have been renamed View/Animate and View/Playback. The Window/Change Colors command has been moved to the Format/Color command.

0. The Books menu has been removed. You can open an Electronic Book by choosing Open Book from the Help menu. To access the book annotation commands, open a book, and click on the book window with the right mouse button to see a context menu containing the annotation commands.

0. The Help menu offers picks for Mathcad Help, the Resource Center, and Using Help. The Desktop Reference and Tutorial Electronic Books have been integrated into the Resource Center, the Sampler Electronic Book has been removed, and Technical Support Help has been removed.

8. Troubleshooting

Java applets while browsing files on the World Wide Web

If you browse to a web page containing a Java applet while browsing the Web using the Resource Center, Mathcad could cause an illegal application error because of a problem in the current version of Microsoft's Java virtual machine. To prevent this, we recommend that you disable Java programs in your copy of Internet Explorer or refrain from browsing the Web through the Resource Center until this problem is corrected.

Please take the following steps to disable Java if you are running Windows 95 or NT 4.0 (NT 3.51 users are not affected):

0. Run Internet Explorer from the Windows Start menu.

1. Choose Options from the Internet Explorer View menu.

2. Click on the Security tab.

3. Click "Enable Java Programs" so it is no longer checked.

Microsoft is currently working to correct this issue inside Internet Explorer. Once a updated version of the Java virtual machine is available, information on how to download it will be posted on http://www.mathsoft.com/ .

DDE interface

The Dynamic Data Exchange (DDE) interface in Mathcad is no longer supported. To communicate with other applications, Mathcad now provides components. See the chapter "Data Management" in the Mathcad User's Guide as well as the on-line Resource Center and \SAMPLES folder for examples.

Scripting an object using VBScript and JScript

The versions of VBScript and JScript installed with the version of Microsoft Internet Explorer (v. 3.02) provided with Mathcad should not be used to script the Scriptable Object component. You must download current versions of VBScript and JScript from http://www.microsoft.com/vbscript and http://www.microsoft.com/jscript.

Variable names and SI units

The SI unit system is now available as the default unit system in Mathcad 7, giving you access to standard SI unit names (including single-letter abbreviations such as A for ampere, N for newton, etc.). Take care when defining variables in Mathcad worksheets not to redefine built-in unit names in the SI system. Choose Unit from the Insert menu to browse a list of units in the default unit system of your worksheet.

Multiple uses for quote key

The quote (") has many uses in Mathcad 7. In a blank space in the Mathcad worksheet it begins a text region. If you have selected a math expression, it introduces the complex conjugate operator. In a math placeholder it begins a string variable.

MATLAB sparse arrays

MATLAB allows you to save a "sparse array" (an array containing rows or columns of zeros) using special "sparse array" notation. Mathcad and MathConnex do not convert the sparse array notation if you import the array with either the File Read/Write component or the Input component; they read in the array exactly as it is stored in the file.

Exporting to dBase files

When you export data from Mathcad or MathConnex to a dBase file, the values are truncated to four decimal places.

Importing data files containing text

If you use the File Read/Write component to import data from a data file whose first row contains text, Mathcad and MathConnex will import the values in the file to 5 decimal places.

Importing data from an Excel data file

Mathcad and MathConnex allow you to import data from a file created in Excel for Windows 95 or earlier. You cannot import data from a file created in Excel for Windows 97; instead, first use Excel to save the data in Excel for Windows 95 format and then import the data into Mathcad or MathConnex.

Error "Unable to set the Value property of the Range class" when using the Excel component

If you use the Excel component in Mathcad or MathConnex and have Excel for Windows 95 installed, you will not be able to pass more than approximately 1800 values to the Excel component.

Accumulate tab in Output Table Properties

In Mathcad the Accumulate tab accessible from the Properties selection of the Output Table context menu is not implemented. The Accumulate tab is, however, implemented in MathConnex.

Unable to print

If your printer has an extremely long name, you could experience a system error when printing from Mathcad. Try shortening the name of the printer icon in the Control Panel to prevent this from happening.

Black boxes appear when printing

If you print a worksheet containing an operator such as a summation, you may see black boxes on the print out if you are printing to a postscript printer. To correct this, use a non-PostScript printer driver that is compatible with your printer.

Text doesn't appear in Print Preview

Gray and silver text does not appear on the screen when you choose Print Preview from the File menu but it will print.

Saving Mathcad 7 worksheets as Mathcad 6 worksheets

When you save a Mathcad 7 worksheet as a Mathcad 6 worksheet, regions or features that won't work in Mathcad 6 are saved as bitmaps. However, these bitmaps may not closely resemble the regions or features if you save the worksheet using 256 colors.

Opening Mathcad 6 worksheets in Mathcad 7

You can open any Mathcad 6 for Windows or Macintosh worksheet in Mathcad 7. In general, the worksheet will maintain its previous appearance. However, live symbolic keywords will be converted into the new symbolic keyword operator in Mathcad, and file associations will be translated into full pathnames. File variable arguments will appear as strings inside data file functions such as READPRN and WRITEPRN.

Uninstall icon in NT 3.51

If you have difficulties using the Uninstall icon to uninstall Mathcad under Windows NT 3.51, you can uninstall Mathcad by deleting the Mathcad directory.

File Write component

The Overwrite and Properties options on the context menu for the File Write component are not supported in Mathcad, only in MathConnex.

Bookmarks for Web documents

When you right-click on a Web page while in the Resource Center and choose Add to Favorites, the page location is added to Internet Explorer's list of Favorites, not to Mathcad's list of bookmarks.

Backtracking while browsing the Web

If you jump to a document from a framed page while browsing the Web using the Resource Center, pressing the Back button brings you to the previously loaded page instead of the framed page.

Difficulties creating an animation or inserting a component

You could experience system difficulties while creating an animation under Windows NT if your TEMP variable points to a folder that does not exist. Make sure the TEMP variable points to an existing, writable folder. To set this variable under NT 3.51, open System Settings in the Control Panel. Under NT 4.0, click on My Computer with the right mouse button, choose Properties, and click on the Environment tab.

Quicksheet examples in the on-line Help

If you run the Mathcad Resource Center from the CD, the Quicksheet Examples in the Mathcad Help will not launch automatically. To open the Quicksheet examples, open the Resource Center, click on Quicksheets, and use the Search button in the toolbar to search on the topic you were looking at in the Help.

Personal Quicksheets

If you created Personal Quicksheets using Mathcad 6, you can open them in Mathcad 7 by choosing Open from the File menu, selecting the Mathcad 7 directory, and typing *.MCU in the File Name. Your Personal Quicksheet will be as a file with the MCU extension.

Mathcad–Axum Link

In Mathcad 6, MathSoft introduced the Mathcad–Axum link, which allows you to create Axum graphs directly in a Mathcad worksheet. With Mathcad 7, we've updated the technology for the link and provided a new way to create it. To use the Mathcad–Axum link with Mathcad 7:

0. Install Axum 5 (dated 5/18/97 or later). You can update your copy of Axum 5 to the version dated 5/18/97 during the installation of Mathcad 7.

1. Refer to the chapter "Data Management" in the Mathcad User's Guide for information on the Axum component, which allows you to create a Mathcad–Axum link. Note that information about the link in the on-line Help in Axum may be out of date.

2. Refer to the on-line Help in Axum for information on the kind of data required for the graphs you wish to create.

If you used the Mathcad-Axum link to create Axum graphs in a Mathcad 6 worksheet, the graphs will convert automatically to graphs using the Axum component when the worksheet is opened in Mathcad 7.

The Mathcad 7–Axum link does not work with Axum 4.1 or earlier.
