Extract
Questions about polynomials can be turned into questions about matrices by associating with the polynomial
(over an arbitrary field) its companion matrix
which has p/an as its characteristic polynomial. This technique is often used in stability theory, as indicated in [1]; companion matrices also occur in the theory of the rational canonical form.
