Automatic file saving when you click away from the Editor
If you are editing a file in the MATLAB Editor that you have saved at least once, new
changes are automatically saved if you click away from the Editor.
This setting is on by default, and is accessible through MATLAB Editor/Debugger
Preferences. On the Home tab, in the Environment section, click Preferences, and
select Editor/Debugger. Disable the setting under Automatic file changes by clearing
the Save changes upon clicking away from a file check box.
