Hello, I have created a GUI to collect some data. This GUI uses some equipment that has to be connected/disconnected to MATLAB with commands. I want to make it so that when you push CTL-C to stop running something any of the functions, the equipment is disconnected properly. Is that possible without using "oncleanup" with putting it in every function used in the GUI?

When you launch the GUI, have a function create an oncleanup, and then have the function uiwait() or waitfor() the gui figure. The control-C will trigger exiting the uiwait() or waitfor(), causing the function to exit, triggering the oncleanup .
... at least in theory.

Hmmm, https://www.mathworks.com/matlabcentral/answers/156803-detection-of-ctrl-c-in-m-file suggests using onCleanup, which agrees with my memory, and when I test the code there it works. But I agree that the onCleanup does not seem to get invoked for ^C for waitfor() or uiwait() so I do not know what the solution is.
