Subject: Filon quadrature for oscillatory integrals

Filon quadrature enables you to numerically integrate functions that look
like
F(x)*sin(n*x)
by "factoring out" the sin term. A lisp function for this is now in
http://www.cs.berkeley.edu/~fateman/temp/filon.lisp
Why write in lisp? Because a generic arithmetic package allows me to use
the same code for single, double, quad-double, or arbitrary precision.
A paper ... ~fateman/papers/oscillate.tex includes a Maxima language
version of the same, also related other pgms.
