I am using Matlab Appdesigner and want to be able to force quiet any callback function and any subfunction with in that callback function. I added a push button to my app named Cancel and put the following code with in the sub-function of the Excute callback function to stop it when I press cancel. However it takes time to quit the excustion of the callback function (Excute) because it doesn't start quiting untill it reaches out to the line where this code is at in the sub-function.

%Check for Cancel button press
if app.CancelButton.Value == true
    app.CancelButton.Value = false; % To reactive the stop button
    return
end

Is there any way to add a Canceling pushbutton to the app which overwrite everything as Ctrl-C does in the Command window?

I never use AppDesigner or timer objects myself either. What code did you try?

I actually still don't know how to start with timer object. However, I used uiconfirm now but still works as my previous code since it need to wait for the excution to reach the line in the subfunction where app.CancelButton.Value is checked.

app.CancelButton.Value = false;
selection = uiconfirm(app.UIFigure,'Cancel?',...
    'Confirm Cancelling'); 
switch selection 
    case 'OK'
        app.CancelButton.Value = true;
        return
    case 'Cancel'
        app.CancelButton.Value = false;   
end
