| 摘 要： | 本文给出了两种N维单纯形上的Blending插值算子。其一在边界上不仅插值函数本身,而且插值它的一阶微商。另一个算子则是一种形式简单的线性算子。本文还研究了二种算子的逼近阶,讨论了提高代数精度的方法并给出了改进型算子。

| Abstract: | In this paper, we give two formulas of the Blending function interpolation
on the N-dimensional simplex. One of them can be interpolated to the function
and its derivative on the boundary of N-dimensional simplex. The other is a
linear interpolation function. This paper also gives the covergence orders of
interpolation by these Blending functions. |
