摘要
本文讨论分段多项式的C2连续保形或保单调插值,在每相邻两个型值点之间,构造一段五次或五次以上的多项式,通过在某些段提高多项式次数,使得这个分段多项式插值函数C2连续且保形或保单调。
This paper discusses the problem of C2 continuous shape-preserving or monotonicity-preserving piecewise polynomials interpolant. A fifth or higher order polynomial piece is constructed between two consecutive data points. By increasing order of polynomial while needing in some intervals, the piecewise polynomials interpolating function is C2 continuous and shape-preserving or monotonicity-preserving.
