I am currently trying to use the gaussian evaluation of integrals but
since I am very lazy I was wondering if those gauss points and weight
were not available directly from a ftp site or if
there would be any of you having a copy of those huge list 
of numbers.

If so can you send me an E-mail at i0c0256@zeus.tamu.edu

Thanks in advance

If anybody does know of a ftp site that carries quadrature nodes and
weights, please post it to the net. I get tired of copying the buggers
out of books, and I am sure others are too.

The numerical receipes package (in fortran at least) has a subroutine which
will calculate those abcisses and weight for any interval and any number of
points.  I don't remember the name of the routine but it's described in the
accompanying book in the numerical integration section. My 0.02$
