.SH NAME
fitgrid \- interpolate 1d and 2d data
.SH DESCRIPTION
Fitgrid is a package for interpolating one dimensional and two
dimensional data. The package has the following functionality:
.br
.sp
1.) Interpolating single-valued functions in one dimension.
.br
2.) Interpolating parametric curves in the plane.
.br
3.) Computing an interpolatory surface through a rectangular grid of functional
values.
.br
4.) Interpolating periodic functions in one dimension.
.br
5.) Finding integrals and derivatives of interpolated functions.
