Using Matlab Please (code answer!), thanks.

1. Fixed Point Method, Newton-Raphson Method, & Secant Method Determine the highest real root of f(1) = 203 - 11.722 +17.7 - 5: - Graphically (Just for checking out) - Use fixed point iteration method (three iterations, to = 2.9). - save the root on HW4-1.dat file - save the estimated error Ea on HW4-2.dat file - show all steps of three iterations by hands. (use an engineering paper.)
