I have a global audioplayer object that is used by two different GUIs.
GUI1.m
global ap;
% functions and stuff...
function toBeCalled(obj, evt, a)
% Timer function for ap
GUI2.m
global ap;
function assignTimerFcn()
% set the TimerFcn for ap
ap.TimerFcn = {@toBeCalled, 2};
I get an error message stating that the function doesn't exist when I play the audioplayer object if the TimerFcn is set this way.
Is there something else I need to specify in order to tell Matlab that I intend to use the toBeCalled function from GUI1.m instead of looking for a toBeCalled function in GUI2.m?
Thanks

If the "toBeCalled" function is a subfunction of the GUI1.m file, you cannot access it directly from anywhere else. Move "toBeCalled" in an own M-file to allow this.
This is not a problem of timers or guis, but the wanted behavior of subfunctions.
