gbinterp - Compute equispaced curve from interpolated

gbinterp [options]

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.

number of equispaced points (default 10)
set the range 'rmin,rmax' (default full x range)
read interpolation points from a file
the interpolation method: (default 0)
linear (requires at least 2 points)
cspline (requires at least 3 points)
Akima spline (requires at least 5 points)
the type of output: (default 0)
first derivative
second derivative
specify the input fields separators (default " \t")
