[comp.lang.pascal] Spline source needed

HE891C%GWUVM.BITNET@cornellc.cit.cornell.edu (The Time Traveler) (11/20/89)

I'm looking for source code (Lightspeed preferred) that will generate
cubic spline functions from a set of data points in three regions and
that creates a close approximation to the profile curves.  It should
use either the "Natural" or "Clamped" boundry conditions.
