optimization

[James Yang]

Dear octave users:

I have little exparience in matlab and new to octave. I tried to find a
function for optimization. For example, I have a function, say
        f(x) = x^2 + 2*x + 5
and I want to find x0 s.t. f(x0) is maximized. I know I can use binary
serch. Does any one know if there is any function and how to use it?
This may be a trival question but it will be of great help to me. Thanks
in advance.
