NAME

6       Fitgrid is a package for interpolating one dimensional and two
7       dimensional data. The package has the following functionality:
8
9       1.) Interpolating single-valued functions in one dimension.
10       2.) Interpolating parametric curves in the plane.
11       3.) Computing an interpolatory surface through a rectangular grid of
12       functional values.
13       4.) Interpolating periodic functions in one dimension.
14       5.) Finding integrals and derivatives of interpolated functions.
