Running multiprocess applications from MATLAB

Question

I\'ve written a multitprocess application in VC++ and tried to execute it with command line arguments with the system command from MATLAB. It runs, but only on one core ---

Answer 1

Run the command outside of Matlab and see how many cores its using. There should be no difference running it from within Matlab because its just a call down to the operating system. IE. equivalent from running on command line.

EDIT

Ok odd, what do you get when you call feature('NumCores') ? What version of Matlab are you using?

Does it help to enable this?
