Is there any alert function in matlab?
My program will display a message on the command window when reaches the end of every loop. (one loop about 200 seconds)
I want to have alert sound if my matlab program doesn't update over a certain time (e.g. 200 seconds) So, I can be notified that my program has problem (run overtime) in that loop.
Thank!!

Try soundsc(). Supply it with a filename of some sound you want it to play.

Thank. But How can I count for the time? (start from last update of the command window) * I cannot put the script of the soundsc() function inside my main program (since sometimes it never stop like a infinite loop)

Are you still having trouble with this? You can use a timer to launch a sound or message box after a certain time. If it finishes before the warning time, you can stop the timer.

Set up a timer at the start of the code i.e.
alert=timer('TimerFcn','beep','StartDelay',200,'Name','Timer-1')
At the start of the loop set the timer running: -
start(alert)
To stop the beep sounding if the loop works, immediately before you display the message on the command line, stop the timer
stop(alert)
