function timecount(~)

start(t)
stat=true;
b=sec;

hour=hour+1;
end
if min==0
fprintf('%s초 \n', num2str(a));
elseif hour==0
fprintf('%s분 \n', num2str(min));
fprintf('%s초 \n', num2str(a));
else
fprintf('%s시간 \n', num2str(hour));
fprintf('%s분 \n', num2str(min));
fprintf('%s초 \n', num2str(a));
end
pause(1)
if sec == 0;
stop(t)
delete(t)
end
end
end
this is whole code of timer.. Input is second that you want to count(ex : 10sec).. when you input 10sec, this function will end after 10sec. but it's not stop and run infinity...

When you define the timer's callback as a string, it is evaluatred in the base workspace. Therefore you cannot observe changes in the variable |stat|inside the show function. Better use a flag which is "attached" to the timer, e.g. its UserData:
t = timer('TimerFcn', @myTimerCB, 'StartDelay', sec, 'UserData', 0);
start(t)
...
while get(t, 'UserData') == 0
...
end
...
function mytimerCB(TimerH, EventData)
set(TimerH, 'UserData', 1);
end
