Write a function fixed-point_iteration that inputs a function g, an initial guess ro, an error tolerance tol, and a maximum number of iterations N, and approximates a fixed point c of g using fixed-point iteration. Your function should estimate error as errxn-2n-1l and halt when err N, whichever happens first. The function signature should be as follows: function [c, n, err] = fixed-point-iteration (g, x0, tol, N) Use your code to solve g(), g: e, for z 1,, with tol 10-10. State your initial guess and how many iterations were needed
