Neet 4.1 only, DO NOT NEED computation , only Matlab code , please provide code.

4.1 Let f (x) = 10(x22 + (1-X1 )2. At x = (0,-1) draw the contour lines of the quadratic model (4.1) assuming that B is the Hessian of f. Draw the family of solutions of (4.3) as the trust region radius varies from = 0 to = 2, Repeat this at x = (0,05). 4.2 Write a program that implements the dogleg method. Choose Bk to be the exact Hessian. Apply it to solve Rosenbrock's function (2.23). Experiment with the update rule for the trust region by changing the constants in Algorithm 4.1, or by designing your own rules
