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.

Variational Quantum Singular Value Decomposition [PDF]

open access: yesQuantum, 2021
Singular value decomposition is central to many problems in engineering and scientific fields. Several quantum algorithms have been proposed to determine the singular values and their associated singular vectors of a given matrix.

No-Reference Image Blur Assessment Based on Response Function of Singular Values [PDF]

open access: yes, 2018
Blur is an important factor affecting the image quality. This paper presents an efficient no-reference (NR) image blur assessment method based on a response function of singular values. For an image, the grayscale image is computed to the acquire spatial

Robustness Analysis of a Class of Decentralized Control Systems [PDF]

open access: yesModeling, Identification and Control, 1986
The paper presents a method for analysing the robustness properties of a class of decentralized control systems. Perturbations both in local and in interconnection parameters are dealt with. The method is based on the use of singular values.

On the singular value decomposition of (skew-)involutory and (skew-)coninvolutory matrices

open access: yesSpecial Matrices, 2020
The singular values σ > 1 of an n × n involutory matrix A appear in pairs (σ, 1σ{1 \over \sigma }). Their left and right singular vectors are closely connected. The case of singular values σ = 1 is discussed in detail. These singular values may appear in
