The General Linear Model and the Generalized Singular Value Decomposition [PDF]

open access: yes, 2009
The general linear model with correlated error variables can be transformed by means of the generalized singular value decomposition to a very simple model (canonical form) where the least squares solution is obvious.

Perturbation bounds for eigenvalues of diagonalizable matrices and singular values

open access: yesJournal of Inequalities and Applications, 2016
Perturbation bounds for eigenvalues of diagonalizable matrices are derived. Perturbation bounds for singular values of arbitrary matrices are also given. We generalize some existing results.

Singularity, Wielandt’s lemma and singular values

open access: yesJournal of Computational and Applied Mathematics, 2010
The authors obtain some upper and lower bounds for the largest and the smallest singular values of certain complex matrices based on the entries and diagonal dominance. A relationship between largest singular value of a block matrix and its block norm matrix is obtained. Numerical examples are given to demonstrate the usefulness of their results.

Stability-Margin-Oriented Key Parameter Design for Voltage-Source Rectifiers in Weak Power Grids With Inductive Impedance

open access: yesIEEE Open Journal of the Industrial Electronics Society, 2021
Voltage-source rectifiers (VSRs) have been widely used in modern power grids. The inductive grid impedance of the power grid poses a serious threat to the stability of the VSR.

The singular values of the GOE

open access: yesRandom Matrices: Theory and Applications, 2015
As a unifying framework for examining several properties that nominally involve eigenvalues, we present a particular structure of the singular values of the Gaussian orthogonal ensemble (GOE): the even-location singular values are distributed as the positive eigenvalues of a Gaussian ensemble with chiral unitary symmetry, while the odd-location ...

Bound for the largest singular value of nonnegative rectangular tensors

open access: yesOpen Mathematics, 2016
In this paper, we give a new bound for the largest singular value of nonnegative rectangular tensors when m = n, which is tighter than the bound provided by Yang and Yang in “Singular values of nonnegative rectangular tensors”, Front. Math.

An S-type singular value inclusion set for rectangular tensors

open access: yesJournal of Inequalities and Applications, 2017
An S-type singular value inclusion set for rectangular tensors is given. Based on the set, new upper and lower bounds for the largest singular value of nonnegative rectangular tensors are obtained and proved to be sharper than some existing results ...

Determinantal inequalities of Hua-Marcus-Zhang type for quaternion matrices

open access: yesOpen Mathematics, 2021
In this paper, the authors extend determinantal inequalities of the Hua-Marcus-Zhang type for positive definite matrices to the corresponding ones for quaternion matrices.
