Hi,
I'm a newb to using App Designer. I've built the GUI that works wonderfully, and can open it programmatically from my main .m script. However, I cannot for the life of me figure out how to force the .m script to wait for the App GUI to close. I figure it has something to do with assigning modality in App Designer. I've tried using a waitfor indexing with a variable written to my base workspace from the app to no avail. I've tried using a while condition, also to no avail. Are there any ways to make the main script wait for the app to close before continuing?

Hello Frankie,
Here's an example how to do it.
app = NameOfApp;
while isvalid(app); pause(0.1); end

no the figure opens at that command and closes on the CloseRequestFcn

If it's made by guide and can be detected by gca, you can try with the code below, otherwise, see step 2 of this answer
fig = gca;
if isvalid(fig)
waitfor(fig);
end
You can try removing CloseRequestFcn, write a public function so you could close it in your script.
