sensitivity analysis

Fmincon was used to optimize the objective function and results are obtained successfully.I don't know how to use Matlap for postoptimality analysis i.e: checking the effect of changing constraint limits on the optimum function, effect of scaling the obj. function on the Lagrange multipliers, and finally the effect of scaling a constraint on its lagrange multiplier.

I recommend this simple Matlab code for implementation of Monte Carlo method for sensitivity analysis of Simulink models: http://www.mathworks.com/matlabcentral/fileexchange/47758-sensitivity-analysis-in-simulink-models-with-monte-carlo-method
