How can I find maximum of a function in MATLAB?

How can I find the maximum value of a function in MATLAB? And that function has some subject to constrain criteria also.

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?

This question is addressed in the documentation. In more than one place.

How do I set these kinds of Subject to k, m ϵ N s ϵ [0, 1] my maximum function? How to model it belong to Natural number in Matlab and belongs to only 0 and 1 in Matlab?
