**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-Ithe points where the interpolation is computed are read from a file.

**OPTIONS**

-nnumber of equispaced points (default 10)-rset the range 'rmin,rmax' (default full x range)-Iread interpolation points from a file-Mthe 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)-Othe type of output: (default 0) 0 interpolation 1 first derivative 2 second derivative-Fspecify the input fields separators (default " \t")-hprint this help-vverbose mode
