gbinterp1
Compute equispaced curve from interpolated
Usage
gbinterp [options]
Overview
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.
