摘要
综合分析了N.Dyn提出的四点法以及其他几种构造插值型曲线的细分方法.提出了一种新的细分方法,这种细分格式含有4个调节参数,通过对参数的选择,可以得到N.Dyn的经典四点法、非均匀四点法、Hassan三进制四点法等几类重要的细分方法.同时对这种细分格式给出了数值实验.
This paper makes an comprehensive analysis of the four-point method of N.Dyn as well as several other curve interpolation method,and presents a new subdivision method which contains four adjustable parameters format.Through selecting the parameters,we can obtain N.Dyn classic four-point method,non-uniform four-point method,Hassan ternary four-point method and so on.At the same time,the numerical experiments are given for this scheme.
