Newton Raphson method.

This code computes the roots of non linear equation using Newton Raphson method.

This code computes the roots of non linear equation using Newton Raphson method.
before running the code write syms x in the command window then enter the following:
newton(F,xi,iter,rerr), where F is non linear function, xi is the initial guess, iter is the number of iterations and rerr is the relative error in percentage.
