startbtn_Callback

The startbtn_Callback function calls the start method of the timer object if the

timer is not already running.

if strcmp(get(handles.timer, 'Running'), 'off')

start(handles.timer);

end

stopbtn_Callback

The stopbtn_Callback function calls the stop method of the timer object if the timer

is currently running.

if strcmp(get(handles.timer, 'Running'), 'on')

stop(handles.timer);

end

figure1_CloseRequestFcn

The figure1_CloseRequestFcn callback executes when the user closes the app. The

function stops the timer object if it is running, deletes the timer object, and then

deletes the figure window.

if strcmp(get(handles.timer, 'Running'), 'on')

stop(handles.timer);

end

% Destroy timer

delete(handles.timer)
