A(i,1) = sum(B(i,:)) + C*3;
I have function A as above. I wan t to maksimize this function. How can I do this?
Thanks.

What is C? Which value do you want to optimize?

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?

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

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.
