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.
OPTIONS
- -n
- number of equispaced points (default 10)
- -r
- set the range 'rmin,rmax' (default full x range)
- -I
- read interpolation points from a file
- -M
- the interpolation method: (default 0)
- 0
- linear (requires at least 2 points)
- 1
- cspline (requires at least 3 points)
- 2
- Akima spline (requires at least 5 points)
- -O
- the type of output: (default 0)
- 0
- interpolation
- 1
- first derivative
- 2
- second derivative
- -F
- specify the input fields separators (default " \t")
- -h
- print this help
- -v
- verbose mode
