Convert SBML model into simulatable Matlab function

I'm looking for a tool to convert a SBML model into a simultable Matlab function. I've tried SBMLTranslate() function from libSBML but this returns a Matlab struct, not a function, and therefore it would require some effort to make simulatable. Does anybody know if such tool exists? The idea is that I want to optimize the system of ODE's using some experimental data and one of the various Matlab global optimization algorithms, or MEIGO.
