RATIONAL SPLINE ROUTINES
Rational Spline Subroutines for Adjustment of Tension Parameters
Scientific data often contains random errors that make plotting and curve-fitting difficult. The Rational-Spline Approximation with Automatic Tension Adjustment algorithm lead to a flexible, smooth representation of experimental data. The user sets the conditions to apply no tension; to apply fixed tension; or to determine tension with a tension adjustment algorithm. The user also selects the number of divisions (knots) in the data set, the knot abscissas, and the allowed maximum deviations from line segments. The subroutines use an automatic adjustment scheme which frees the user from the drudgery of adjusting individual tension parameters while still giving control over the local behavior of the spline.
