How to get a return value(or exit code) from matlab

I'm trying to retrieve some value from my matlab script just so I can let the system know whether the program worked successfully or not. I'm running the matlab script from the window command line. Also, I wanna send the value through the whole pipeline. Do you have any good idea? Thank you so much in advance.

What exactly is "the whole pipeline"? If you post the command, adjusting it is much easier.

What about writing a file inside Matlab and using its contents from the Windows Command prompt?

Use a function instead of a script for flexibility.

function yourFunction(OutFile)
   ... do what ever you want
   fid = fopen(OutFile, 'w');
   if fid == -1
      error('Cannot open output file')  % Bad bad bad - you cannot see this in the caller!
   end
   fprintf(fidm 'success\n');
   fclose(fid);
end

The run in Windows' command prompt:

matlab -r "yourFunction('C:\Temp\Output.log')"

Now e.g.

set /p Build=<C:\Temp\Output.log

can catch the output.

Another option is to start Matlab with an output file and parse this later:

matlab -wait -logfile output.log
