SPLINE.rar - SPLINE is a package of simple routines for setting up and evaluating splines and related functions, whose goal is either to
to interpolate given data exactly at a set of points
to approximate data over an interval.
There are a variety of types of splines available, including least squares polynomials, divided difference polynomials, piecewise polynomials, and various B, Bernstein, beta, Bezier, Hermite and Overhauser splines.
Also included are a set of routines that return the local "basis matrix", which allows the evaluation of the spline in terms of local function data.

FEMPACK---Finite-Element-Routines.rar -
FEMPACK is a collection of some simple routines for implementing the finite element method. The emphasis is on simplicity and clarity. Currently, only the 2D case is handled, with a choice of low order triangular and quadrilateral elements.,2011-11-13 12:21:11,下载5次
