Linear system matrices of rational transfer functions

Froilán M. Dopico, María C. Quintana, Paul Van Dooren

In this paper we derive new sufficient conditions for a linear system matrix $$S(\lambda ):=\left[\begin{array}{cc}T(\lambda )& -U(\lambda )\\ V(\lambda )& W(\lambda )\end{array}\right],$$ where $T(\lambda )$ is assu…
