Write a MATLAB function, called Newtons_method that takes as inputs a function, f, it’s derivative f’, an initial guess 20, an error tolerance, tol, and a maximum number of iterations, N, and outputs the root of f obtained using Newton’s method (denoted by c), starting with 20. Your function should have an error defined by err= |In – In-1), 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:
