I already did that and found no answer to my question at any of these links:
http://en.wikipedia.org/wiki/Orthogonal_polynomials http://mathworld.wolfram.com/HermitePolynomial.html http://en.wikipedia.org/wiki/Hermite_polynomials
If the answer was so easy to find using Google, why did you take the trouble to write a reply without providing a link? You have a rather eccentric concept of "helpfulness."
Thanks anyway!
