There is no way to use the GUI to interrupt a routine without its cooperation.
Your stop_Callback should set a value in a shared area. Your realtimefunction routine should sometimes fetch the current version of the value, and exit if it finds it has been asked to stop.
For example,
function start_Callback(hObject, eventdata, handles)
set(hObject, 'UserData', false);
realtimefunction(handles);
function stop_Callback(hObject, eventdata, handles)
set(handles.start, 'UserData', true);
function realtimefunction(handles)
...
while true
drawnow(); %give a chance for interrupts
need_to_stop = get(handles.start, 'UserData');
if ~isempty(need_to_stop) && need_to_stop;
break;
end
...
end
%now clean up as needed

That is not what the comments say. As you inform me that you are having problems executing the code, I must presume that the comments describe the way that the code is intended to operate and that any code that does not work that way is incorrect code that you were asking me to repair.
In any case you can easily remove the test I put in about framecount < 100

Hello,
Have the same problem but I did not catch nothing from above. Where I can read more about starting and stopping real time functions in APP designer?
