If you want to do that properly, the directory (on Windows post XP) where to save the preferences would be:
fullfile(getenv('APPDATA'), yourprogramname) %and NOT matlab!
if you want the settings to get propagated to other domain computers the user log onto, or
fullfile(getenv('LOCALAPPDATA'), yourprogramname)
if the settings are local to the user and machine. IF the settings are the same to all users, then:
fullfile(getenv('PROGRAMDATA'), yourprogramname)

As a complete alternative to Guillaume's correct answer:
"Note: Preference values are persistent and maintain their values between MATLAB sessions. Where they are stored is system dependent."
These would be per-user.
By the way: I have found in practice that one of the real challenges of preference files is backwards compatibility. "Oh, gosh, a phi of 1.69 isn't even possible now! But if they had that in their preferences file 4 years ago then they must have been doing this kind of analysis and that requires interpreting the other preferences a completely different way...."
