MATLAB Installation Guide for Unix

Saving Your MATLAB Environment

When you install a new product, the installer regenerates your path file, pathdef.m, and your printing and documentation preference files, printopt.m and docopt.m, respectively. If you've modified these files, the installer does not delete them. Instead it puts them in the $MATLAB/toolbox/local/old directory and renames them. The installer appends the date and a version number to the file name. For example, the saved version of to pathdef.m could be pathdef.m.4july2002.1.

To reuse your previous path file or preferences file, swap the newly created files with these saved versions, restoring the saved version of the file to its original name.

Note    When reusing an old pathdef.m file, you may need to add new products that you just installed.
