Matlab editor is not working

Dear all

My Matlab R2022b is not showing functions on Editor on MacBook. I can run the code and get some results but it is not showing the scripts that is written in editor.

What should I do?

To me it seems like not a very common problem. Please let me know if the issue still persist.

It is still exist and I dont know how to deal with this problem.

I've had the same issue over 3 macs (intel and silicon), multiple iOS and multiple versions of Matlab over the last 2 years or so. It seems to be related to RAM - if I close every other application then the scripts are more likely to show. However, when I attempt to open Matlab I generally have plenty of spare RAM - it's not under particular pressure. Matlab has full disc access. Once a script is displays it stays displayed even when opening all the applications I previously had open and increasing memory useage again.

This seems to be common enough that other people have been bringing it up since last year. You can see if any of these threads are any help. I don't have a Mac or any of these versions, so can't test any of this myself.

Hello,

Someone in my company got the same issue.

running Matlab in -nodesktop mode, then launching the editor with edit, seemed to improve the situation.

I suffered blank editor window, sluggish startup, and related problems after upgrading my 3 GHz 6-Core Intel Core i5 Mac Mini to OSX 14.6.1 Sonoma.

I found that System settings -> Privacy & Security -> Full Disk Access -> MATLAB_R2024a was not set.

Setting it (i.e. turn on full disk access for Matlab) solved the problem.
