Is this referring to the parallel toolkit ?

You cannot control the activity of an external program from inside Matlab reliably. A soltuion would be to allow the external program to set a kind of flag, when it is finished, e.g. writing certain data to a specific file. Do you have an access to the external program?

if you use system() to invoke the external program, then if the program does not start up graphics windows, then system() will not return until the program finishes.
