I have 6 scripts that save images in different directories. I am not able to make parpool work or actually, maybe I don't understand how to make it work. To just test it, I wrote a file say a.m, that just had

varA=5 and b.m that just had 
varB = 10

I then said

parpool('AttachedFiles',{'a.m','b.m'})

I got this output Starting parallel pool (parpool) using the 'local' profile ... connected to 4 workers.

ans = 
   Pool with properties: 
              Connected: true
             NumWorkers: 4
                Cluster: local
          AttachedFiles: /home/scripts/matlab_dir/a.m
                         /home/scripts/matlab_dir/b.m
            IdleTimeout: 30 minute(s) (30 minutes remaining)
            SpmdEnabled: true

What I don't understand is why is not printing the output? Am I missing out something? Should I make some changes if I am writing a for loop for iterating through the images and storing them?

Is there any other alternative to run four .m files paralelly in matlab?
