Way too late for an answer here, but my solution for really long running codes was to add this to the end of my long running codes.

load handel
sound(y,Fs)

There are infinitely many possible sounds. A few that have been provided in MATLAB by default are listed by:

>> help audiovideo
Audio and Video support.
Audio input/output objects.
  audioplayer   - Audio player object.
  audiorecorder - Audio recorder object.
Audio hardware drivers.
  sound         - Play vector as sound.
  soundsc       - Autoscale and play vector as sound.
Audio file import and export.
  audioread     - Read audio samples from an audio file.
  audiowrite    - Write audio samples to an audio file.
  audioinfo     - Return information about an audio file.
Video file import/export.
  VideoReader   - Read video frames from a video file.
  VideoWriter   - Write video frames to a video file.
  mmfileinfo    - Return information for a multimedia file.
Utilities.
  lin2mu        - Convert linear signal to mu-law encoding.
  mu2lin        - Convert mu-law encoding to linear signal.
Example audio data (MAT files).
  chirp         - Frequency sweeps          (1.6 sec, 8192 Hz)
  gong          - Gong                      (5.1 sec, 8192 Hz)
  handel        - Hallelujah chorus         (8.9 sec, 8192 Hz)
  laughter      - Laughter from a crowd     (6.4 sec, 8192 Hz)
  splat         - Chirp followed by a splat (1.2 sec, 8192 Hz)
  train         - Train whistle             (1.5 sec, 8192 Hz)

So train contains a train whistle. Your default choices in MATLAB are chirp, gong, handel, laughter, splat, train. My choice for a long code would be handel, becuase it seems singularly appropriate. However, I suppose the choice for a code that runs a long time, and then fails would best be splat.

You could create your own sound from your own favorite choice. Perhaps the sound of a foghorn you might find posted on the internet.

A simple way I use to get notified that processing had finished was to add a "beep" to the end of the program (I was usually in the other room watching TV, so it worked for me). Just bear in mind that the beep will either mean your code has finished =) or your code stopped with an error =(.

Edit

At the command line, type:

beep

If you do not hear a sound, type:

beep on

Then test to see if beep works by typing "beep" one more time. If that doesn't work, then make sure your speakers are on loud enough that you can hear it.

thanks for your help. I wrote 'beep on' and also set speakers on high volume, but I didn't hear any voice. my program is as followed:

clc; clear;

T=3 ; M=5 ;

for t=1:T

for i=1:M

for j=1:M

b{t}(i,j)=1/sqrt(2*pi*i)*exp(-1/(2*t)*(j-i)^2);

end

beep on

What can I do??

Dr. Seis 2012-1-30

"beep on" simply turns on the beep functionality (if it was off). Just in case you have beep turned off elsewhere, your last line should be:

beep on; beep;

You could create a function that plays the audio and call it at the end

Or you could have it send you an email at the end of processing:

If you search in the File Exchange for "Alarm" there are other implementations that throw up dialogs, etc.
