How can I retrieve an exit code from a stand-alone created using MATLAB Compiler 4.10 (R2009a)?

I would like to execute the stand-alone from a batch file and do some processing according to the returned exit code.

In order to return an exit code to the command interpreter, use the MATLAB function EXIT, as follows:

function hello
disp('hello');

exit(3) % Return exit code 3.

You will be able to access the exit code in the batch file through the variable %ERRORLEVEL%, however, in order for this to work, you will need to run the stand-alone using the Windows command "start" with the option /WAIT, as in the following example:

 @echo off
 start /WAIT hello.exe
 echo %ERRORLEVEL%
