How can I pause the matlab script until I've closed a matlab app?
In my case, I've an app that serves to select the input of my calculations, but while I'm choosing the input the script continues to run. I need to suspend the script until the user has finished to select the input.
What can I do?

My script in matlab is this
d=fopen('nomi piattaforme.txt');
c=textscan(d,'%s','Delimiter',',');
run scelta.mlapp
a=1;
...
In the app, the lines the make it close are:
% Button pushed function: ConfermaButton
function ConfermaButtonPushed(app, event)
assignin('base','producer',app.Prod_selection.Value)
assignin('base','panel',app.Panel_selection.Value);
assignin('base','platform',app.Platform_selection.Value);
delete(app.Selezione)
end
In 'scelta.mlapp' the user must choose through 3 dropdown menu the parameters that I need for the next steps. Actually, I haven't write my complete code yet, but, anyway I need to get the three outputs before 'a=1'.
e.g.: once, in the script, I tried to use one of these parameters some lines below, and it gave me an error saying that 'panel' was not defined yet, beacuse it actually doesn't exist yet, I haven't yet chosen the parameter from the app.
I hope that it is clearer

Now I tried to use a 'flag' in this way, and it's quite satisfying:
flag=0;
d=fopen('nomi piattaforme.txt');
c=textscan(d,'%s','Delimiter',',');
run scelta.mlapp
while flag==0
pause(5);
end
a=1
And at the end of the app I assigned to 'flag' the value 1 with "assignin".
Maybe it is not the smartest way, but it works enough...

There is indeed cleaner way, as explained here:
my_app_handle = my_app;
uiwait(my_app_handle.UIFigure_property)
disp("hello")
hello
