"program terminated" message by mail

AHMET ANIL DINDAR — Tue, 15 Jul 2008 22:22:02 -0400

Hi,
I've been doing a long-hours-run analysis in MATLAB in which
I used "sendmail" in several parts of the script with the
intention of having been informed about the process. It
worked superb till now.

However, my analysis program terminates due to several
reasons. At such moment, I follow the incoming mails and
find the last action in the process. Is it possible to write
a code that runs my program and checks whether it is running
or not? And in case of termination the code sends an e-mail
message.

Any idea?

thanks in advance.

Yes.

The ease of doing so will depend greatly upon which operating
system you are using, which you have not stated. It would
be automatic in Unix if you start the Matlab run using the "batch"
command.

Thanks for the answer. I didn't know the OS was important
for such a program since I'm not an expert on programming.
Anyway, I'm using XP in my comp. Is there still a chance to
use the "batch" command?

thanks again.

One thing you could possibly do is put a try/catch block in
your mainline that encompasses all of your code. And then on
any errors you can send an email notifying the source and
reason of the error.

In the catch block you could do something like:

catch
  err = lasterror;

  error_message = sprintf('Error: %s::%s\nOccured in %s::%s
at line %d\n', err.identifier, err.message, err.stack.file,
err.stack.name, err.stack.line);

  sendmail('uhoh@itdied.com', 'Matlab process crashed',
error_message);
end

NOTE: I've not run this code so treat it as pseudocode

Dear Rodney,
What you adviced me was what I exactly I was looking for.

Thank you for your help.

greetings from Istanbul.

%%% try-catch example %%%
the example code
clc,clear,close all
a=1:1:10;
try
    counter=1;
    for i=1:length(a)
        ali(counter,1)=a(i,1);
        counter=counter+1;
    end
    plot(ali)
catch
    adem=lasterror ;
    disp(adem.message)
end
%%% thanks rodney %%%
