Adding worker to matlab pool without closing?

Hey,

I'm running test runs on a cluster to see what kind of speed ups I get when using a specific dictionary learning algorithm.

Basically, I'm running the code after opening up increasingly bigger matlab pools (1,2,3,4...24). Every time I need to increase the number of nodes, however, I need to close the matlab pool and then open it again with the next bigger number. This seems to be taking a good bit of time.

My question is - is there a way to simply add a worker to an open matlab pool or do I have to close it every time?

I answered below. How long is it taking to open your matlabpool? What scheduler are you using?

There is no way to add a worker to an existing matlabpool. You must close it every time.
