All-Pass Functions for Mirroring Pairs of Complex-Conjugated Roots of Rational Matrix Functions

Wolfgang Scherrer, Bernd Funovits

We construct rational all-pass matrix functions with real-valued coefficients for mirroring pairs of complex-conjugated determinantal roots of a rational matrix. This problem appea…
