This script uses Halley's method to compute the positive k zeros of the Bessel function of the first kind J(n,x) and second kind Y(n,x) where n is a positive number. The routine has been tested for up to k=100 and n=100.

The guess function has been improved so the script is more robust. Also I have added bessel functions of the second kind.
