Tips

  • To restore the default preferences for a given release of MATLAB, delete all of the files in the corresponding preferences folder. Use the prefdir command to determine the full path of the preferences folder.

    For example, to restore the default preferences for R2021a, type prefdir in the Command Window to determine the location of the preferences folder.

    prefdir
    ans =
        'C:\Users\username\AppData\Roaming\MathWorks\MATLAB\R2021a'
    Close MATLAB, delete all of the files in the folder C:\Users\username\AppData\Roaming\MathWorks\MATLAB\R2021a and then start MATLAB again. MATLAB starts with all preferences set to their default values.

    One file to consider keeping is history.m. For more information, see Set Command History Preferences.

Introduced before R2006a
