Factorization of Singular Matrices

Proceedings of the American Mathematical Society, 1992
We give a necessary and sufficient condition that a singular square matrix A A over an arbitrary field can be written as a product of two matrices with prescribed eigenvalues. Except when A A is a 2 × 2 2 \times 2 nonzero nilpotent, the condition is that the number of zeros ...

The Antitriangular Factorization of Symmetric Matrices

SIAM Journal on Matrix Analysis and Applications, 2013
Indefinite symmetric matrices occur in many applications, such as optimization, least squares problems, partial differential equations and variational problems. In these applications one is often interested in computing a factorization of the indefinite matrix that puts into evidence the inertia of the matrix or possibly provides an estimate of its ...

Coprime Factorizations of Multivariate Rational Matrices

Mathematics of Control, Signals, and Systems, 2000
Coprime factorization is a well-known issue in one-dimensional systems theory, having many applications in realization theory, balancing, controller synthesis, etc. Generalization to systems in more than one independent variable is a delicate matter: First of all, several non-equivalent coprimeness notions have to be taken into account. Even worse, the
