Why did you unaccept Jan's answer? It is the correct solution. What was wrong with it? Just negate the function, exactly as he said. Then you are minimizing the negative of your function, which maximizes it! So WTP?

I didn't say Jan's answer was wrong. I applied the Jan's answer for my code and obtained the right result. So, there are no problems left.

Matlab contains some tools for minimization. A maximization does exactlly the same, if you change the sign of the optimization criterion.

Jan and John D'Errico thank you both. I applied the solution you suggested above and after a bit of work I maximized the my problem. Thanks again.

In fact, most optimizers seem to be minimization codes. It just seems a logical standard, since often one wants to minimize a sum of squares, perhaps. That may acttually be the most common general class of optimization problem overall anyway. So it makes sense that all optimizers will be consistent, thus minimizers. That way you need not remember which direction some tool works, as opposed to others. And of course, negating a function makes a min into a max, and vice versa.
