I am using matlab

Newton's method to approximate the solution of an equation f(x) 0 is given by the iteration f(%) F(n), k=0, 1,2, , where ro is an initial guess close to the actual solution Use Newtons method to solve for the real solution of f(x) = x-x+1 = 0. Use an initial guess of xo --1. Do this using a while loop with a stopping criterium: errk+
