function [y] = camel6(xx)

% INPUTS: % % xx = [x1, x2] 

x1 = xx(1); x2 = xx(2); term1 = (4-2.1*x1^2+(x1^4)/3) * x1^2; term2 = x1*x2; term3 = (-4+4*x2^2) * x2^2; y = term1 + term2 + term3; end

Input Domain: x₁ [-3, 3], x₂ [-2, 2].

1. for the function given above find the approximated minimum using random walk method

2. use Gradient Descent Method to find (global optimum), initial point [-2,1] (we can select another initial point)

please the answer must be a matlab code, thanks
