Ooh, that's going to get you in trouble (says a fellow Matlab admin).

The short answer is "Not going to happen". There are some packages out
there that let you do parallel "stuff" with Matlab. But, AFAIK, they all
require a Matlab license for each "user" running Matlab (and TMW considers
a "user" to be user at host).
The standard answer at this point is that it's time to go to "real code"
And, really, it's a good answer. When I looked at parallelizing Matlab
code, the effort involved was actually comparable to re-implementing it in
parallel in a "real" compiled language.
