On Kronecker products, tensor products and matrix differential calculus
The algebra of the Kronecker products of matrices is recapitulated using a notation that reveals the tensor structures of the matrices. It is claimed that many of the difficulties that are encountered in working with the algebra can be alleviated by paying close attention to the indices that are concealed beneath the conventional matrix notation. The vectorisation operations and the commutation...
متن کاملPerturbation Analysis of Coupled Matrix Riccati Equations
Local and non local perturbation bounds for real continuous time coupled algebraic matrix Riccati equations are deriv ed using the technique of Ly apunov majorants and xed point principles Equations of this type arise in the robust analysis and design of linear control systems
متن کاملGIP integrators for Matrix Riccati Differential Equations
Matrix Riccati Differential Equations (MRDEs) are initial value problems of the form: X 0 1⁄4 A21 XA11 þ A22X XA12X; Xð0Þ 1⁄4 X0: These equations arise frequently throughout applied mathematics, science, and engineering. It can happen that even when the Aij are smooth functions of t or constant, the solution X may have a singularity or even infinitely many singularities. This paper shows severa...
متن کاملMatrix Differential Calculus with Applications to Simple, Hadamard, and Kronecker Products
Several definitions are in use for the derivative of an mx p matrix function F(X) with respect to its n x q matrix argument X. We argue that only one of these definitions is a viable one, and that to study smooth maps from the space of n x q matrices to the space of m x p matrices it is often more convenient to study the map from nq-space to mp-space. Also, several procedures exist for a calcul...
متن کاملHadamard, Khatri-rao, Kronecker and Other Matrix Products
In this paper we present a brief overview on Hadamard, KhatriRao, Kronecker and several related non-simple matrix products and their properties. We include practical applications, in different areas, of some of the al-
