function [r,resarray] = newton(f,df,x0,tol,maxiter)

%f = @(x) x^3-3

%df= @(x) 3*x.^2

%x0= 1

%tol=10^-6

%maxiter= 100

resarray = [];

x=x0;

h = (f(x))/ (df(x));

i = 1;

while(abs(h) > tol & i<=maxiter)

h = f(x)/ df(x);

x = x - h;

resarray = [resarray, x];

i=i+1;

end

r = x;

end

 ....
 for i = 1:maxiter
  if abs(h) <= tol
    break
  end
  ....

Sorry. I have corrected it to be a for-loop.
