MATLAB: How to trigger repetitive events in appDesigner? I’d like to control with a “start, pause, stop” state button, but any loop I start seems to need to finish before appDesigner re-looks at the state of the buttons.

I'd like to control the triggering of multiple function calls with a "start, pause, stop" state button, but any loop I start seems to need to finish, before appDesigner re-looks at the state of the buttons. Is there a different kind of function I need to be writing? Do I need to somehow initiate multiple threads?

Geoff Hayes had a helpful answer in "How to interrupt a While loop in appDesigner by pushing a button. I added a pause (0.001) in the loop and it now functions correctly - Thanks Geoff!

Instead of a button, you can change it to a state button in app designer

Then in your code just use a while loop to check the value of the state button is 1 before continuing with the rest of your code.


while(app.statebutton.Value ~=1) 
    pause(1);
end
app.statebutton.Value = 0; 
%rest of your code

MATLAB: Interrupt a timer wait function

Do not create and start the timer every iteration and wait for it: create and start it once with an indefinite repeat. Have the cancel callback stop() the timer.
