Abstract

This paper proposes three different procedures for matrixvalued rational interpolation of a function  F (z), where F:C→CN×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.

Key words：  matrixvalued rational interpolation; Lagrange interpolation; scalar product of matrix
