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
It is pointed out that the main results in a recent paper by Kano (1987) have previously been published in the literature. IN KANO (1987), necessary and sufficient conditions are given for the existence and uniqueness of positive definite solutions to the algebraic Riccati equation and asymptotic s
