摘要
本文基干三次样条插值的基本原理,运用互为反函数一阶导数的倒数关系,提出用光滑曲线插值平面点序列的分段三次样条插值算法。
According to the basic theories of cubic spline numerical method and the recip(?)al relation of first derivative between funetion and inverse function,this paper puts forward a method to divide plane sequential points into several subsequence and fit all points smoothly with cubic spline numerical method.
