how to know the rate of convergence here
i know the formula
$\displaystyle \lim_{n->\infty}|\frac{e_{n+1}}{e_n^m}|=c$
where m is the convergence rate
but it doesnt help me here at all

See here for Newton's method. You can simply insert a counter in your for loop like:
i=0
(in for)
i = i+1;
end
You'll find it converges very fast.
