NAME

Fitgrid is a package for interpolating one dimensional and two dimensional data. The package has the following functionality:

1.) Interpolating single-valued functions in one dimension.
2.) Interpolating parametric curves in the plane.
3.) Computing an interpolatory surface through a rectangular grid of functional values.
4.) Interpolating periodic functions in one dimension.
5.) Finding integrals and derivatives of interpolated functions.
