Do you know if is it better to supply the gradient using 'fminunc'? For better I mean the time spent for analysis, and its accuracy.

I'm not an expert on this, but I believe that if you don't provide the gradient function, then it has to be numerically estimated from your function. Thus providing the gradient (if available) can help the algorithm to converge faster.
