单调光滑函数的保形插值算法

The Interpolation Algorithm of Shape Preserving for Monotonic Functions

对于给定的单调数组,本文描述了一种保形二次插值样条函数。插值函数结构简单、计算方便。最后估计了插值函数的误差。

For a given sequence of monotonic data, a shape preserving quadric interpolation spline function that is simple to construct and easy to calculate is described in this paper. The error estimates for the interpolation spline functions are given and the approximate precision is O(h^2).
