how break loop in execution?

i can write a piece of my code:

appp = uifigure;
appp.Position = [500 500 300 75];  
BB = uiprogressdlg(appp,'Message','Calcunate Simulation','Indeterminate','on');
drawnow;
x=1000;
for i=1:x
    ....
        .....
        BB.Value = count/n_Loop;
    BB.Message = sprintf('Calculate Simulation Equity %d/%d cycle',count,n_Loop);
end

close(BB);
close(appp);

if I want to interrupt the cycle while it is running (with banner running) how can I do it?

Is it possible to add a "Stop" button? and how implement it? (i want to avoid ctrl+c in the editor)

Set the uiprogressdlg 'Cancelable' property to 'on' when it is created. Then in the loop, check the 'CancelRequested' property, and break out of the loop if it is true.

appp = uifigure;
appp.Position = [500 500 300 75];  
BB = uiprogressdlg(appp,'Message','Calculate Simulation','Indeterminate','on','Cancelable','on');
drawnow;
x=1000;
for i=1:x
    if BB.CancelRequested
        break
    end
    % ....
    % .....
    BB.Value = count/n_Loop;
    BB.Message = sprintf('Calculate Simulation Equity %d/%d cycle',count,n_Loop);
end
close(BB);
close(appp);

I use "if nested" and I used "return" instead of "break"..it's better

another question: I see to use uiprogressdlg is slows down the loop for me.. is it implemented correctly or is there something faster to know how long it is until the loop exits

Updating the progress bar takes time; that's what slows down the loop. Instead of updating its Value and Message on each iteration of the loop, you can update every 10 or 100 iterations, which would save some time.
