DFP Quasi-Newton for Quadratic Function

i tried multiple times with the tutorial from mathwork about quasi-newton but always failed, maybe my Matlab R2015b is not match with the functions from tutorials. please help me

f(x; y) = 100*(y-x^2)^2 + (1-x)^2

Implement the procedures for minimization of the function f(x; y) using Quasi-Newton (DFP) method applying Armijo line search with

initial point (x0; y0) = (-0:75; 1)
