How to limit optimization program to choose only natural integers numbers (not float) if my objective function is not linear?

Hello,

I would like to ask you about my optimization problem on matlab:

Is there a function to compute the minimum of a non-linear function by giving us naturals integers values for x belongs to N (x should be an integer which represent a discrete mode 1 or 2 or 10 or anything else, the important is that x is an natural integer and f is reel R).

Thank you in advance!

If you have Global Optimization Toolbox you can use Mixed Integer ga Optimization.
