Rogue *.m file crashing my MATLAB Online
Show older comments
Can someone please help?
I wrote a subroutine to go through 1000 data points that I wanted plotted and accidentally put the "figure" command in the loop. When I ran it, it began to make the 1000 figures and crashed the browser tab. No matter what I try to do to quit MATLAB, when I bring it up again, it automatically re-launches this unfinished *.M file running. I can't get it to just launch fresh. I have tried
- Cntrl+C - that did NOTHING
- going into the https://drive.mathworks.com/files/, correcting the error in the file in a text editor, and uploading the corrected file
- deleting the contents of the Sessions folder within https://drive.mathworks.com/files/
- logging out of MATLAB, clearing the cache and running again
- logging into MATLAB from a totally different browser
- pasting "clear ..." and the *.m fie name as soon as I can, but the subroutine takes over too fast
Can anyone please help? I have wasted one hour just trying to ever get back to using online MATLAB again

Hi Michael,
I faced a somewhat similar issue. I tried a workaround which solved the issue. Here are the steps:
- Reload the MATLAB Online instance and repeatedly press Ctrl + C when the command window is active before it loads the workspace.
- It freezes the editor from opening the file in workspace however, on restarting the MATLAB Online session, similar problem will be encountered. In order to solve it you can choose the Exit MATLAB option by clicking on the top right profile button.
- Now relaunching MATLAB session would solve the issue and it will start afresh.
