How to kill a starved designer app

1 view (last 30 days)
Hi folx,
I'm writing an application using app designer (moved to designer from guide I used in previous projects).
My problem is, that during development I have of course many bugs in the beginning, but some of them causes the app to starve. It is not possible to use a standard close(figure) but it is also not posible to close the window. CTRL-C or CTRL-Break also do nothing. The only solution is to restart matlab (after 20+ seconds of delay).
Thanks for any hints

Note, this closes all figures
close(findall(0, 'type', 'figure'));

Sorry, I missed this. There is no reaction on Ctrl+C or enter. There is a new line on enter, but no new prompt. The only way to kill the app is to use task manager. It takes 1-2 minutes to kill the app including Matlab.

I don't understand well what are you saying here.
There is no reaction on Ctrl+C or enter. There is a new line on enter, but no new prompt.
Once again:
  • if you press ctrl+c or enter, you should see ">>" showing up with each click if MATLAB is not busy (or not responding - frozen)
  • If you press enter and only new lines are apearing, without ">>", then MATLAB is busy doing something, but not frozen. In this case ctrl+c would probably return an error
  • When your app freezes, check task manager if your MATLAB is not responding
Also, there are some unsupported functions between GUIDE and App Designer, so make sure you're using what is supported by the latter. You can also test your app on the other machine, maybe there's something wrong with yours.

Hi Mario,
I did not checked the RAM to be honest. I'll check it tomorrow. My data is about 50 MB in total and I do not have many programmes open but Matlab.
Thanks for your help
