定义于双叶双曲面上的多元Lagrange插值问题

Abstract

针对在实际科研生产中经常涉及到的有关定义于双叶双曲面上的多元Lagrange插值问题进行了研究。提出了定义于双叶双曲面上的多元Lagrange插值定义，给出了判定双叶双曲面上的结点组是否构成插值正则结点组的判定定理以及迭加构造方法，最后通过算例对所得方法进行了实现。 The multivariate Lagrange interpolation problem, which is usually defined on the hyperboloid of two sheets, is often studied in practical scientific research and production. Multivariate Lagrange interpolation is proposed to define the definition of hyperboloid of two sheets, given to determine whether the node group on an hyperboloid of two sheets forms judgment theorem and superposition method to construct interpolation regular set of nodes, finally is to implement the method.
