Comments und Rebuttal advantage indicated. He is quoting to this effect reference (3). This paper deals, though, with discrete systems and the Lyapunov equation of the type shown in'its title, while our paper (4) concerns continuous systems. Such systems are mentioned in (3) in a brief remark only,
A new method of explicit direct solution for the Lyapunov matrix equation is proposed. Based on a fundamental property allowing the decomposition of any arbitrary matrix into symmetric and skew-symmetric parts, the Lyapunov matrix is expressed in a simple and compact form. In addition, a sign$cant r
With the help of the Kronecker map, a complete, general and explicit solution to the Yakubovich matrix equation V -AV F = BW , with F in an arbitrary form, is proposed. The solution is neatly expressed by the controllability matrix of the matrix pair (A, B), a symmetric operator matrix and an observ
