NAME
csagrid - cubic spline approximation
DESCRIPTION
Csagrid is a software package in the ngmath library that implements a cubic spline
approximation algorithm to fit a function to input data. The input for the approximation
is a set of randomly-spaced data. These data may be one-dimensional, two-dimensional, or
three-dimensional.
The output is a set of values at coordinates on a user-specified grid, or at a set of
user-specified points (including at a single point).
Functionally equivalent Fortran, C, and NCL interfaces are provided.
Csagrid is based on the work of David Fulker and his package Splpack.
