提出3种方法解决函数F(z)的矩阵值有理插值问题,其中F:C→C^N×N,并给出相应算法来选择具有指定极点插值式的插值节点.最后，给出数值例子验证该方法的有效性.

This paper proposes three different procedures for matrixvalued rational interpolation of a function  F (z), where F:C→C^N×N, and devises an algorithm for selecting interpolation points of rational iterpolants with prescribed poles. Additionally, a numerical example is used to demonstrate effectiveness of the presented methods.
