alarm for finishing running of a program

Hi all

I've written a program and it's so time-consuming. I want to write a command for the programe that alarm me the program runnning has been finished.

How can I do it?

thanks,

[avss matlb]

I am currently working on a fire detection project after detecting fire it sends mail but my video player or webcam stop working.Please, can anybody know how to solve this problem?

Answer 1

[John D'Errico]

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)

[Felix Lauwaert]

You are awesome. I'll have it in all my long-running programs. I haven't even tried out beep or other boring stuff. Please somebody to select this answer as the good one to close this question!

Thanx , i just waked up my neighbour and now he angrily knocking on my door :(

[John D'Errico]

Why? He could not Handel the noise? If the sound on your computer is too loud, then the solution is easy. Just lower the sound volume. What actual sound you make is irrelevant.

perfect

[YIN JEH NGUI]

This really made my day!!!! I will definitely include this in my looping scripts haha

[Isabella Osetinsky-Tzidaki]

Following this perfect solution, you may love either "gong" or "chirp" and you may play with Fs as well. E.g. I would prefer: load chirp, sound(y,1/2*Fs)

[Goku]

So cool! Where can I see the list of possible sounds?

[John D'Errico]

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.

[Philipp Schneider]

If you want to avoid loading files:

sound(sin(1:3000));

will give you a plain sinus sound.

[Erik Kruit]

Philipp really great!

ah ah ah !!! so funny !

Answer 2

[Dr. Seis]

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.

dear Elige

as you told, I added "beep" at the end of program, but it doesn't work.

What can I do??

[Dr. Seis]

see edit above

[som]

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

end

end

beep on

What can I do??

[Dr. Seis]

"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;

Answer 3

[Jason Ross]

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.

Thank You Sir.I got its solution. I had taken .wav file and I got the beep sound. Thank you Sir for your help.
