Journal of Computational and Applied Mathematics, 1991 Typical matrix eigenvalue problems, quadratic or linear, are best formulated as pencils \((A,M)\) in which both \(A\) and \(M\) are real and symmetric. This fact is emphasized in the paper through a set of physical examples. Then, the canonical forms are used to explain the role of the sign characteristic attached to real eigenvalues.

MathematicsWe derive a double-optimal iterative algorithm (DOIA) in an m-degree matrix pencil Krylov subspace to solve a rectangular linear matrix equation. Expressing the iterative solution in a matrix pencil and using two optimization techniques, we determine the

Ray pencils of general divergency
African Vision and Eye Health, 2009 That a thin refracting element can have a dioptric power which is asymmetric immediately raises questions at the fundamentals of linear optics. In optometry the important concept of vergence, in particular, depends on the concept of a pencil of rays ...

Equivalence of Matrix Pencil and HTLS Ring-Down Electromechanical Mode Identification Algorithms
IEEE Access, 2023 Matrix pencil and Hankel total least squares (HTLS) are two popular ring-down electro- mechanical mode identification algorithms. The appeal of these algorithms can be attributed to faster execution due to the non-iterative procedure of model order ...

Poles Extraction of Underwater Targets Based on Matrix Pencil Method
IEEE Access, 2020 The majority of the sonic frequency bands used in active sonar detection and identification are within the resonance region of the target. The poles of target are very important characteristics of the resonance region. This paper analyzes and studies the

Matrix pencils completion problems II
Linear Algebra and its Applications, 2008 [For part I see the author, ibid. 428, No.~1, 259--304 (2008; Zbl 1131.15010).] The paper deals with the matrix pencils completion problem. This problem analyzes the existence of a matrix pencil with prescribed Kronecker invariants and a regular subpencil. Specifically, the author studies the following problem: Let \(A(\lambda) \in F[\lambda]^{n \times

Canonical form of symplectic matrix pencils
Linear Algebra and its Applications, 1998 Es seien \(E, A, K\in \mathbb{R}^{2n\times 2n}\), und \(K\) sei regulär und schiefsymmetrisch. Die Schar \(P(s, t)= sE- tA\), mit \(s\), \(t\in\mathbb{C}\) besitzt \(z_0\in\overline{\mathbb{C}}\) als Eigenwert, wenn es \(s_0, t_0\in \mathbb{C}\) mit \(z_0= s_0/t_0\) und mit \(\text{det }P(s_0, t_0)= 0\) gibt. Das Paar \((P(s, t),K)\) heißt symplektisch,

Improving the Accuracy of the Pencil of Function Method Increasing Its Matrix Polynomial Degree
MathematicsThe estimation of complex natural frequencies in linear systems through their transient response analysis is a common practice in engineering and applied physics. In this context, the conventional Generalized Pencil of Function (GPOF) method that employs
