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
