On the inversion of rational matrices

Abstract

The method developed herein provides a convenient procedure for the inversion of rational matrices-matrices whose entries are rational functions in <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">s</tex> which at <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">s = 0</tex> are nonsingular.
