close all; clear; clc;

%menentukan opsi optimisasi
options = optimoptions(@fminunc,'Display','iter','Algorithm','quasi-newton');
%menentukan guess value
xy_guess = [0,0];
%memanggil algoritma optimisasi
[xy_opt, fval] = fminunc(@rosenbrock_func,xy_guess,options)
%fungsi objektif
function f = rosenbrock_func(in);
x = in(1);
y = in(2);
f = 100*(y-x^2)^2 + (1-x))^2
end

For example fminunc in that code, there's fminunc too in matlab R2015b buat it doesn't work. Or i have made mistake? And then rosenbrock function. I don't know what it calls in matlab R2015b

What does "it doesn't work" mean, precisely? Show us...

Your code above includes the definition of rosenbrock_func. You must place that code in its m-file of that name in a location on your matlabpath; functions are not defined in the command wlndow inline.
