A compound matrix algorithm for the computation of the Smith form of a polynomial matrix
This paper presents a numerical method for the exact reduction of a single-variable polynomial matrix to its Smith canonical form without finding roots and without applying unimodular transformations. This technique uses the notion of compound matrices and produces a stable and accurate numerical algorithm working satisfactorily for any polynomial matrix of any degree. Numerical results of several examples are given.
