In article <27575.2770d581@kuhub.cc.ukans.edu>, arritt@kuhub.cc.ukans.edu asks
for "plain-vanilla f77" sources for cubic spline interpolation.

Doctor FORTRAN is happy to recommend the excellent collection of routines from
Carl deBoor's _Practical_Guide_to_Splines_. I understand that it is available
from netlib, with the name "pppack" (the first two ps in the name derive from
"piecewise polynomial). You can get a brief description of the routines in this
package by sending a one line e-mail message ("send index from pppack") to one
of the netlib sites. You will be sending mail to a machine, so try to avoid
getting tricky. General information on netlib may be obtained by sending the
line "send index".

For folks in the US, the best location is probably AT&T Bell Labs in Murray
Hill, New Jersey. The preferred address is "netlib@research.att.com".

I have used this package on DEC VAX/VMS, IBM PC, and even an old Apollo DN560
workstation. I have had no complaints. As far as documentation goes, well, I
imagine the idea is that you purchase a copy of deBoor's book. I don't know if
it is still in print, but it is in many academic libraries. The publisher is
Springer-Verlag, if my memory is correct.
