MATLAB: Editor saving .m file when switching between editor tabs.

editorsavingtabs

I'm using MATLAB R2014b and I've recently been working with several files open at once in the editor window. However, I didn't notice until just today that if I have unsaved changes in one file and switch to a different tab, those unsaved changes are now saved. Most of the time this isn't a problem, but if I hadn't caught it today I would have done some serious damage to one of my scripts. Is there a way to disable this feature? I like to know when I am deliberately saving a file (aside from backups).

See the last item in the Desktop section of the Release Notes for MATLAB for release R2014b for instructions on how to turn this behavior off in the Preferences.

MATLAB: Recover former state of Matlab Editor

Hi Matt,

Actually, Yair Altman has already mentioned this https://undocumentedmatlab.com/articles/recovering-previous-editor-state

It looks like the info about the editor data, at least on Windows, is kept in file MATLABDesktop.xml

winopen(prefdir)

On the bottom of the file you can find the files that will be opened the next time you start the MATLAB. When you close the file in Editor, the xml file automatically updates and then this .m file won't be opened in Editor the next time.

There's also file MATLABDesktop.xml.prev, which probably stores the same file but from the previous version. Which might be what you're looking for. If you opened/closed MATLAB more than twice with different files open in Editor, then data about previous files is probably lost.
