This example then specifies a smoothed spline interpolation method on the GRID statement. As shown by the following output, the resulting surface plot is smoother still. libname reflib ...

It can also be useful to explore why cubic-spline interpolation is more appropriate for motion control than, say, interpolations involving higher order polynomials. The primary reason is one of ...

All the grid points can be calculated in this manner. Local interpolation procedures can be categorized into three major classes: nearest neighbours, inverse distance weighting, and splines. However, ...
