WebJan 1, 1976 · Abstract. This paper is a continuation of the paper [1] of the same name by the first author in which it is shown how values of B-splines and their derivatives can be computed by stable algorithms ... The library provides subroutines for 1D-6D interpolation and extrapolation using B-splines. The code is written in modern Fortran (i.e., Fortran 2003+). There are two ways to use the module, via a basic subroutine interface and an object-oriented interface. Both are thread safe. See more The core routines for the subroutine interface are: The ink routines compute the interpolant coefficients, and the val routines evalute the … See more In addition to the main subroutines, an object-oriented interface is also provided. For example, for the 3D case: Which uses the default "not-a-knot" end conditions. You can also specify … See more The library also contains routines for computing definite integrals of bsplines. There are two methods (currently only for 1D): 1. Basic version: db1sqad (integral in the object-oriented interface) -- Computes the integral on … See more The library optionally supports extrapolation for points outside the range of the coefficients. This is disabled by default (in which case an error code is returned for points outside the bounds). To enable extrapolation, … See more
