How to use app2 to control the buttons of app1 in app designer?

The two apps are linked, and then I wrote a lot of things in the buttons in app1. App2 wants to directly control and press the buttons of app1, and then read the global variables. I don't know if there is any implementation method. Thank you

• Do you run your apps in the same instance of MATLAB?

If yes, set tags, or unique names for your apps in Component Browser, under UIFigure - Identifiers, and get their handles this way:

%%  in your script
app1 = get(findall(0, 'Tag', 'AppUIFigure1'), 'RunningAppInstance');
app2 = get(findall(0, 'Tag', 'AppUIFigure2'), 'RunningAppInstance');

This way, you have access to both apps.

If no, I wouldn't know how to find the other running MATLAB instance.

• What about simplifying your problem into having a single app with two windows?

Note: don't use global variables, it's unnecessary.
