Hi Gollapinni,
usually by finding the minimum of "-f". How to do this depends on your function. Good starting point is fminsearch, or, if you have constraints, fmincon from Optimization Toolbox.

Hi Titus,
So I multiply my function with - to find the minimum? Because solvers in the Optimization Toolbox are aiming for minimization but I am looking for maximization. So how can I do this? Any tips?
