Hi Rafael,

1. Locate the MATLAB preferences directory for your user account.

In MATLAB 8.6 (R2015b), the default location of the preferences directory is at the following location:

C:\Users\{username}\AppData\Roaming\MathWorks\MATLAB\R2015b (on Windows)
    /home/{username}/.matlab/R2015b (on Linux)
    /Users/{username}/.matlab/R2015b (on Mac)

In MATLAB 8.8 (R2016b) and later, the default location of the preferences directory on Macs has changed:

/Users/{username}/Library/ApplicationSupport/MathWorks/MATLAB/R2016b

You can also run the following command in the MATLAB command prompt in order to locate your preferences directory:

>> prefdir

This is where your "matlab.prf" file is located. Your path may be different depending on how your system is setup. The preference directory may be hidden in some operating systems.
