NEWTON RAPHSON FUNCTION

% Function :
% X = newtonraphson(fun_str,Start_Point)
% Finds the root of an equation by NEWTON-RAPHSON METHOD.
%
% x(n+1) = x(n) - (F(x(n))/diff(F(x(n)));
%
% INPUTS :
% Eqn_Str : The equation whose root has to be find.
% Eqn_Str Should be an string format.
% Example :
% if F(x) = x^4 - x - 10
% the Eqn_Str = 'x^4 - x - 10';
%
% Start_Point : Initial value of root X ==> x0
%
% Max_Iter : Maximum number of iterations
%
% OUTPUT :
% X : Estimeted root of Equation.
