MATLAB Installation Guide for PC    

Upgrade Installations

Always install MATLAB in a new installation directory, even for upgrade installations. The installer creates a new installation directory for each release by default, for example, MATLAB6p5. You do not need to delete an existing MATLAB installation before installing R13. You can run multiple versions of MATLAB on the same system.

Upgrading and MATLAB Preference Files

MATLAB stores your preference information, such as command history and help favorites, in preference files. The installer does not overwrite these preference files if they already exist on your system. Multiple MATLAB installations on the same system will use the same preference files.
