gbinterp 6.2                                        June 2021                                        GBINTERP(1)

       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.

       gbinterp - Compute equispaced curve from interpolated

-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
