Pseudospectra of Loewner Matrix Pencils
, 2022 Loewner matrix pencils play a central role in the system realization theory of Mayo and Antoulas, an important development in data-driven modeling. The eigenvalues of these pencils reveal system poles. How robust are the poles recovered via Loewner realization?

Matrix pencil-based analysis of multirate simulation schemes
International Journal of Electrical Power & Energy SystemsThis paper focuses on multirate time-domain simulations of power system models. It proposes a matrix pencil-based approach to evaluate the spurious numerical deformation introduced into power system dynamics by a given multirate integration scheme ...

A new localization set for generalized eigenvalues
Journal of Inequalities and Applications, 2017 A new localization set for generalized eigenvalues is obtained. It is shown that the new set is tighter than that in (Numer. Linear Algebra Appl. 16:883-898, 2009). Numerical examples are given to verify the corresponding results.

Equivalent circuit model of electromagnetic behaviour of wire objects by the matrix pencil method [PDF]
Serbian Journal of Electrical Engineering, 2008 The electromagnetic behaviour of thin-wire objects is an important engineering problem. A general analysis of such objects is done according to the moment method approach within an antenna-based electromagnetic model.

Matrix pencils completion problems
Linear Algebra and its Applications, 2008 The paper deals with matrix pencils completion problems. In general, this problem consists in the study of possible Kronecker invariants of a matrix pencil (i.e. its strict equivalence class), when a subpencil is prescribed. Specifically, the author studies and solves the following problem: Let \(F\) be a field.

Classical orthogonal polynomials and Leverrier-Faddeev algorithm for the matrix pencils sE−A
International Journal of Mathematics and Mathematical Sciences, 2006 In this contribution we present an extension of the Leverrier-Faddeev algorithm for the simultaneous computation of the determinant and the adjoint matrix B(s) of a pencil sE−A where E is a singular matrix but det(sE−A)≢0. Using a previous result by the

Coding Prony’s method in MATLAB and applying it to biomedical signal filtering
BMC Bioinformatics, 2018 Background The response of many biomedical systems can be modelled using a linear combination of damped exponential functions. The approximation parameters, based on equally spaced samples, can be obtained using Prony’s method and its variants (e.g.
