For unbounded minimization of a function with potentially many variables use fminunc or fminsearch. The two functions use different internal algorithms and some knowledge of the objective function is ...

Note that by checking the value of nargoutthe function can avoid computing gwhen funis called with only one output argument (in the case where the optimization algorithm only needs the value of fbut not g). WebSpeci cally, we set the GradObj option to on, which tells fminunc that our function returns both the cost and the gradient. This allows fminunc to use the gradient when minimizing the function. Furthermore, we set the MaxIter option to 400, so that fminunc will run for at most 400 steps before it terminates. florida vs oral berts prediction
