Inverse polynomial matrix approximation
Jerzy Kisilewicz
Abstract
A computational algorithm for matrix C(z) which approximates the inverse of a given matrix Y(z) is described in this paper. Finite degree polynomials as the entries of the matrices C(z) and Y(z) are assumed. The sum of squares of coefficients of polynomials, which are the elements of difference C(z)Y(z) – Iz^{–h} is assumed as a criterion of the approximation quality, where I is an adequate unit matrix.
