Description

1) Implementation of B-spline functions; 2) Implementation of an algorithm for determining the B-spline coefficients of a sequence of regularly-sampled data; 3) Implementation of spline-based interpolation with mirror boundary conditions. In all three cases, the spline degree is arbitrary. The determination of the B-spline coefficients proceeds by a signal-processing approach (filtering) rather than by the more conventional matrix-inversion approach.
