Running compiled fortran codes with a matlab wrapper

Here's a head scratcher. I've written a matlab wrapper for a compiled fortran code that accepts input arguments by defining a wrapper function using a series of "system" calls. The issue is, it's fairly slow, and I was wondering if there exists a way to run the compiled fortran on a GPU from matlab, if that makes sense. The fortran is the forward model step in a Markov Chain based inversion scheme (for those familiar with inverse theory). Thanks
