[MATLAB] matlabpool and parfors looking in CPU?

It seems that whenever I run matlabpool, I only see “4 labs”, operational. I guess this is acceptable given that I have a quad-core computer. Is there any way I can explicitly force matlabpool to look for my GPU (Titan X) and operate on its CUDA Cores?

Note: I have CUDA installed.

Just found this:

Apparently the above can’t be done.
