Change Java memory for MATLAB through text?

It seems I've screwed up. I changed the java memory in MATLAB properties to 4GB (I have 16GB on the comp) and now MATLAB does not run. Is there a way to revert this in a .ini file or something? I do not have administrative rights so a method which does not require one would be great. However if the only way is with administrative rights then I can probably work something out.

Thanks

The modifications are stored in matlabprefs.mat in the prefdir in the user path (unless you modified java.opts, which would require admin rights, however).

To find the location of your prefdir, start Matlab without java.

  1. Open a terminal/command window
  2. Navigate to your Matlab installation (if it is not already on the path)
  3. In the bin directory, start matlab -nojvm
  4. Run the command prefdir
  5. Close Matlab, navigate to the prefdir folder and clean out the preferences to reset Matlab, and start over. If there is something important in the preferences, add back the files one by one until you break Matlab again.
