Implement Newton's method and the Secant method in Matlab in seperate m-files. You should use the function header given for each below (b) Secant method function root = secant (f, x0, x1, maxit) % Usage: secant(f, x0 , x1, maxit) % This method uses the secant method to % find roots of f with maximum number of % steps maxit using initial estimates x0 and x1. % The function returns the vector ,root, that contains the % successive approximations obtained by the Secant method
