.SH NAME
gbinterp \- Compute equispaced curve from interpolated
.SH SYNOPSIS
.B gbinterp
[\fI\,options\/\fR]
.SH DESCRIPTION
Compute the interpolating function of user provided data on a regular mesh.
Data are read from standard input as couples (X,Y). The interpolation (x,
f(x)) is printed for x in [rmin,rmax]. When rmin=rmax print a single value.
With option \fB\-I\fR the points where the interpolation is computed are read from
a file.
