please run this method on your matlab program and writing correct method...to comment

clear all;
clc
a=input('enter fun')
f=inline(a)
x(1)=input('enter first guess: ');
x(2)=input('enter second guess: ');
n=input('enter tolerance: ');
iteration=0;
i=2;
while (abs(x(i))> n )
    x(i+1)=x(i)-f(x(i))*(x(i)-x(i-1))/(f(x(i)-f(x(i-1))));
    if (f(x(i+1))~=0)
        i=i+1;
        iteration=iteration+1
        root=x(i)
        break
    else
        root=x(i)
        iteration=iteration
        break
        break
