Improved matrix pencil methods [PDF]
Conference Record of Thirty-Second Asilomar Conference on Signals, Systems and Computers (Cat. No.98CH36284), 2002 We study the problem of estimating signal parameters from a noisy data sequence containing superimposed damped sinusoids. We propose three novel methods by combining the reduced-rank Hankel approximation and the matrix pencil method. We demonstrate that two of the proposed methods significantly outperform both the original matrix pencil method and the ...

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.

A randomized multivariate matrix pencil method for superresolution microscopy [PDF]
ETNA - Electronic Transactions on Numerical Analysis, 2019 The matrix pencil method is an eigenvalue based approach for the parameter identification of sparse exponential sums. We derive a reconstruction algorithm for multivariate exponential sums that is based on simultaneous diagonalization. Randomization is used and quantified to reduce the simultaneous diagonalization to the eigendecomposition of a single ...

Projection Method for Eigenvalue Problems of Linear Nonsquare Matrix Pencils [PDF]
SIAM Journal on Matrix Analysis and Applications, 2021 Eigensolvers involving complex moments can determine all the eigenvalues in a given region in the complex plane and the corresponding eigenvectors of a regular linear matrix pencil. The complex moment acts as a filter for extracting eigencomponents of interest from random vectors or matrices.
