man gbinterp (1): 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
