Write a Matlab function, called fixed_point iteration that inputs a function, SgS, an initial guess x_0, an error tolerance, tol, and a maximum number of iterations, N, and outputs the fixed point of g, obtained using the fixed point iteration, starting with x_0. Your function should have an error defined by E Ix_nx {n-1) I, and stop when the error is less than the tolerance, or if the number of iterations exceeds N - whichever happens first. Your function header should look something like function [c.nerr fxed point iteration(g.x0.tol,N) Use the code you developed in Problem 4 to find the solution to the equation x ef-x, with an accuracy of 1010) for x in [-1, 1 State your initial guess, and how many iterations it took. Plot on the same graph, y gx) and y = x
