Padé逼近问题的数值代数求解

Solving Padé Approximation Problem with Numerical Algorithm

主要讨论使用单点Padé逼近、多点Padé逼近和混合Padé逼近等三种方法将Padé逼近问题转化为数值代数问题,并通过一个数值例子说明如何利用转化后的矩阵方程求解Padé逼近问题.

In this paper the Padé approximation problems were transformed into the corresponding linear system problems. Three procedures were developed to get the linear systems with coefficient vectors. A numerical example is given to illustrate the validity of the procedures.
