Hi all guy.
I displayed it in GUIDE matlab. it work good. However, it don't run when i callback function
other
Timer(handles);%call timer
function Timer(handles)
while find(get(0,'children')==handles.figure1)
nows = fix(clock);
timerStr = [num2str(nows(4)),':', num2str(nows(5)),':', num2str(nows(6))];
set(handles.time,'String',timerStr);
pause(1);
end

You have an infinite loop. The pause() call permits the infinite loop to be interrupted by a GUI callback, but the code in the infinite loop will not continue running until the callback returns. Using pause(1) does not mean that 1 second later, no matter what MATLAB is doing, that control should be given back to your infinite loop.
What you should do is create a timer object that should run evern 1 second. The code for that timer object should update the GUI clock, and then should return.
I think you will find code for a clock in the File Exchange.

He already suggested the solution: use a timer object.
