Re: [Axiom-mail] Using NAG routine d01ajf

[Alasdair McAndrew]

Thanks for that.  So does this mean that numerical quadrature is not supported in Axiom?  I suppose this means I'll have to write my own routine... unless there's some way a freely available numerical package can be ported to Axiom.

It's a  bit of a long story. Basically, this stuff only works for the
commercial NAG product. It consists of AXIOM library code, AXIOM system code
(interpreter), an AXIOM separate process ("nagman") and a remote RPC service
daemon ("nagd") that compiles, links and runs a program that calls the
FORTRAN NAG Library on some remote machine where one has a licensed
implementation of the library.
