.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.
