Installing Release 12.1 on UNIX Workstations (MATLAB Installation Guide for Unix) MATLAB Installation Guide for Unix     Specify Documentation Viewing Options Using MATLAB preferences or the docopt.m option file, you can specify either of these two documentation viewing options: The browser used to view the MATLAB online documentation The location of the documentation If MATLAB supports its Java-based desktop on your UNIX system, you can use the MATLAB desktop preferences mechanism to specify the values of these options. (By default, MATLAB uses the desktop's Help browser to display HTML documentation.) To modify these documentation viewing options, choose the Preferences option on the MATLAB File menu and select the Help option. (See the Release Notes for R12.1 for information about platform support for Java.) If MATLAB does not support the desktop on your UNIX system, you can specify values for these options by editing the docopt.m M-file, located in the $MATLAB/toolbox/local directory. Use this options file to specify an alternative Web browser, additional initial browser options, or a different initial path to the viewable documentation. Viewing Documentation The documentation commands available at the MATLAB command prompt are: doc Starts the MATLAB Help browser help function Displays M-file help for function helpwin Displays a list of MATLAB help topics in the Help browser helpdesk Starts the MATLAB Help browser, which provides access to the full documentation set, including HTML and PDF formatted documents Viewing the PDF files requires the Adobe Acrobat Reader.
