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?

You created the parallel pool but you have not given it any work.
See spmd and see parfeval and see batch
