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 ...

In this paper, it is proved that splines of order k (k ≥ 2) have property SAIN. The proof of this result is based on the important properties of B-splines. Journal Information This monthly journal, ...

The SPLINE method fits a cubic spline curve to the input values. A cubic spline is a segmented function consisting of third-degree (cubic) polynomial functions joined together so that the whole curve ...
