Symbolic matrix inversion with application to electronic circuits

Abstract

The problem of inverting matrices that contain as entries polynomials in several variables is considered. A method of inversion based on the multidimensional discrete Fourier transform of matrix sequences is developed. The method is particularly effective for a moderate number of symbolic variables. An example is given to illustrate its application to an electron amplifier.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
