sll_m_spline_1d Module Reference

Description

Module for 1D splines, linear combination of B-spline functions.

Here we define a 1D spline type as an element of the linear space given by the span of the given B-splines (basis functions). Therefore, initialization of a 1D spline object requires an existing B-splines object, to which a private (polymorphic) pointer is associated. The B-spline coefficients are stored in a public allocatable array; at initialization the array is allocated to the proper size and all values are set to zero. In most situations the B-spline coefficients are not set directly by the end user, but are computed by some other object (e.g., a Poisson solver or a spline interpolator). Various public methods allow the user to evaluate the 1D spline S(x) and its derivative ∂S(x)/∂x any position x.
