I am working on a Matlab script, trying to implement a Simulated Annealing algorithm to obtain once and again the eigenvalues from a Simpack model.

What I want to do is to generate some new parameters in Matlab, then, copy those parameters and paste them as Subvars in the model that I have in Simpack. So, the question is, how can I modify Simpack Model's Subvars from Matlab, refresh the model and run Simpack's Eigenvalue Solver again, with the modified model?
