Currently, I'm using surrogateopt from the global optimization toolbox to minimize a computationally expensive objective function (using third party computer code). I'm wondering, is it possible to get a function handle of the optimized surrogate function or at least the functional form and corresponding coefficients? I've checked the manual and the only thing, which I've found are the functional values at the evaluated points but not the function itself. In one of the help pages in the manual, it's mentioned that the surrogate is a radial basis function. If one can't obtain the surrogate function handle, could one retrieve the coefficients of the surrogate somehow?
Thank you so much for your help
