To resolve this issue, try the following steps:
- Make sure that the write permissions for the MATLAB preferences directory is present, one can do this by running the command ‘prefdir’ in the command window. The output should be the path to the preferences directory. If not, change the permissions using the ‘chmod’ command.
- Make sure MATLAB is set to save preferences when it exits. Check this by going to Preferences -> MATLAB -> General -> Confirm exit. Make sure the "Save changes to layout and settings on exit" option is selected.
- Try resetting the MATLAB preferences to its default values. One can do this by running the command ‘matlabprefs reset’ in the command window. This will reset all preferences to their default values, as a result any previously set custom preferences may get deleted.
- If none of the above steps work, try manually editing the MATLAB preferences file. The preferences file is located in the preferences directory and is called "matlab.prf". Open this file in a text editor and make changes to the preferences directly.
I hope this helps. Let me know if you have any further questions, I’ll be happy to assist you.
