Implement Newton's method and the Secant method in Matlab in seperate m-files. You should use the function header given for each below (a) Newton's method. function root - newton(f, fprime, x0, maxit) % Usage: newton(f, fprime, x0, maxit) % This method uses Newton's method to % find roots of f (with derivative function fprime) % with maximum number of steps maxit % using initial estimate xo % The function returns the vector ,root, that contains the % successive approximations obtained by Newton's method
