Hi there,

I need to compute Associated Legendre Polynomials of higher orders with l between 100 and 120 and m between 10 and 20. I've written a set of C# routines that seem to give me meaningful functions. There are a few problems, however.

First I see no match with the same by this

which is a Japanese (Casio) website. Their values are at variance with mine by a wide margin. The graphics they plot do not seem to look like ALP at all.

So, I am wondering if anybody out there has any experience with such computations and can comment.

Thanks.
