Factoring Matrices into the Product of Circulant and Diagonal Matrices

Journal of Fourier Analysis and Applications, 2015
This paper deals with decomposing a square complex matrix into circulant and diagonal factors. A complex \(n \times n\) circulant matrix \(C\) takes the form \[ C=\left( \begin{matrix} c_0 & c_{n-1} & c_{n-2} & \cdots & c_2 & c_1 \\ c_1 & c_0 & c_{n-1} & \cdots & c_3 & c_2 \\ c_2 & c_1 & c_0 & \cdots & c_4 & c_3 \\ \vdots & \vdots & \vdots & &\vdots & \

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 ...

On the factorization of rational matrices

IEEE Transactions on Information Theory, 1961
Many problems in electrical engineering, such as the synthesis of linear n ports and the detection and filtration of multivariable systems corrupted by stationary additive noise, depend for their successful solution upon the factorization of a matrix-valued function of a complex variable p .

On the factorization of scattering matrices, chain matrices and transfer matrices

Annali di Matematica Pura ed Applicata, 1975
Sia J una matrice (finita) Hermitiana di elementi reali, tale che J 2=1. Una matrice S(p) (p=x+iy) e detta J-contrattiva reale, se per essa valgono, nel semipianoRe p>0, le relazioni(0.1), (0.2) e (0.5). Denotiamo col simbolo CRJ la famiglia di queste matrici.

Parallel Factorizations for Tridiagonal Matrices

SIAM Journal on Numerical Analysis, 1993
Summary: The authors analyze the problem of solving tridiagonal linear systems on parallel computers. A wide class of efficient parallel solvers is derived by considering different parallel factorizations of partitioned matrices. These solvers have a minimum requirement of data transmission. In fact, communication is only needed for solving a ``reduced
