Root-Clustering Criteria (II): Linear Matrix Equations
Department of Mechanical Engineering, Technion Israel Institute of Technology Haifa, Israel
We present the second part of our root-clustering investigation. Given A
Cnxn and A
C, we search for a criterion assuring the inclusion
(A)
A. In this paper we study a criterion based on linear matrix equations (LME), a method generalizing the Lyapunov criterion. We point out some similarities to the composite-matrix approach and comment on the largest class of regions for which the LME approach is valid.
