Calculation of Interpolating Natural Spline Functions Using de Boor's Package for Calculating with B-Splines.

摘要

A FORTRAN subroutine is described for finding interpolating natural splines of odd degree for an arbitrary set of data points. The subroutine makes use of several of the subroutines in de Boor's package for calculating with B-splines. An ALGOL W translation of the interpolating natural spline subroutine and of the required subroutines of the de Boor package are also given. Timing tests and accuracy tests for the routines are described.
