NAME
gbinterp - Compute equispaced curve from interpolated
SYNOPSIS
gbinterp [options]
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 -I the points where the interpolation is computed are read from a file.

- -r
-
set the range 'rmin,rmax' (default full x range)
- -I

- -F
-
specify the input fields separators (default " \t")
