Please find attached *.zip file where you can see one example (refer below code)
properties (Access = public)
stop_sim = false;
end
methods (Access = private)
function stopSimulation(app)
app.stop_sim = true;
msgbox('simulation stopped');
end
function startSimulation(app)
i = 0;
while i<=1000000 && app.stop_sim == false
app.display.Value = num2str(i);
pause(0);
i = i + 1;
end
end
end
function StartButtonPushed(app, event)
startSimulation(app)
end
function StopButtonPushed(app, event)
stopSimulation(app)
end
Once the user pushes the StopButtonPushed button, for which the function "stopSimulation" is a callback, then the app fetch the updated properties and the condition to app.stop_sim will be set to true and hence this allows the app to terminate the while loop before reaching 1000000 iterations.

above function will break the loop as soon as you click the stop button right?
