Hello!
Is there any way of calculating the integral of H_n(x) * H_m(x) * exp(c^2 x^2) with x going from infinity to +infinity and c differs from unity. I'm aware that c=1 is trivial case of orthogonality but I'm really having a problem with the general case. (I should say that this isn't a homework assignment, rather curiosity).
Any ideas?
Thanks...
