toms418, a FORTRAN77 code which estimates Fourier integrals of the form integral ( a<=x<=b ) f(x) * cos(wx) dx, or integral ( a<=x<=b ) f(x) * sin(wx) dx, by Bo Einarsson. This is a version of ACM toms algorithm 418.
While the text of many ACM toms algorithms is available online through ACM: http://www.acm.org/pubs/calgo or NETLIB: http://www.netlib.org/toms/index.html, most of the early algorithms are not available. This is one of them. I typed it in.

toms418 is available in a Fortran77 version.
intlib, a FORTRAN90 library which includes routines to do Filon quadrature.
toms353, a FORTRAN77 library which estimates an integral of the form integral ( a <= x <= b ) f(x) cos(w*x) dx or integral ( a <= x <= b ) f(x) sin(w*x) dx using Filon quadrature, by Chase and Fosdick. This is a version of ACM toms algorithm 353.
Original Fortran77 version by Bo Einarsson. This version by John Burkardt.
