Compute equispaced curve from interpolated
Description
GBINTERP
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.

|||
|

|||
|
0 |
interpolation |
|||
|
1 |
first derivative |
|||
|
2 |
second derivative |
|||
|
-F |
specify the input fields separators (default " \t") |
|||
|
