MATLAB Installation Guide for Windows

Saving Your MATLAB Preferences

MATLAB stores your environment preferences, such as command history and Help favorites, in a set of preference files.

By default, the Release 13 uninstaller does not delete these preference files. However, the uninstaller included with MATLAB releases before Release 12.1 deletes these MATLAB preference files. Before removing one of these earlier MATLAB releases, you might want to preserve your preference files.

To find the location of your preferences files, run the prefdir function at the MATLAB prompt. For example, on Windows 2000 systems, prefdir returns

• prefdir
  ans =
  C:\WINNT\Profiles\username.MATHWORKS\Application Data\MathWorks
  \MATLAB\R13
  

where username identifies a particular user. Because preferences are associated with particular users, the uninstaller only deletes the preferences for the user performing the uninstall.

Removing Installations That Use Dongles

In some installations, MATLAB requires a dongle. A dongle is a hardware-based security device that attaches to the serial or parallel printer port of a desktop computer. It uses embedded codes and passwords to control access to software applications.

If your system uses dongles, the uninstaller asks if you want to delete the dongle drivers. If other applications you run on your system use dongles, do not delete these drivers. For more information, see Troubleshooting an Installation That Uses Dongles.
