Minimal bases of matrix pencils and coprime matrix fraction descriptions
IMA Journal of Mathematical Control and Information, 2002 There are four main approaches that have emerged so far for the construction of a coprime matrix fraction description (MFD) of a proper rational matrix: (a) a method defined by Rosenbrock, (b) the reduction to the block Hessenberg form (BHF) or the block Frobenious form (BFF), (c) the minimal design problem (MDP), and (d) a method defined by Wolovich ...

Delayed matrix pencil method for local shear wave viscoelastographic estimation
Computer Methods and Programs in Biomedicine UpdateShear wave (SW) elastography is an ultrasound imaging modality that provides quantitative viscoelastic measurements of tissue. The phase difference method allows for local estimation of viscoelasticity by computing the dispersion curve using phases from ...

The matrix pencil as a tunable filter
Journal of Magnetic ResonanceDespite inherent sensitivity constraints, nuclear magnetic resonance (NMR) plays an indispensable role in probing molecular structures and dynamics across scientific disciplines. Remarkably, while extensive efforts have targeted instrumental and experimental sensitivity improvements, comparatively little focus has been dedicated to sensitivity ...

Multi-Object Feature Extraction in Resonance Region Based on Short-Time Matrix Pencil Method
Remote SensingAs an intrinsic characteristic of the target, the pole characteristic of the resonant region is solely determined by the target itself and remains invariant with respect to external factors such as the incident direction and polarization of ...

On the Reduction of Singular Matrix Pencils [PDF]
Proceedings of the Edinburgh Mathematical Society, 1935 The following rational method of dealing with the reduction of a singular matrix pencil to canonical form has certain advantages. It is based on the principle of vector chains, the length of the chain determining a minimal index. This treatment is analogous to that employed by Dr A. C.

Structure-Aware Matrix Pencil Method
We address the problem of detecting the number of complex exponentials and estimating their parameters from a noisy signal using the Matrix Pencil (MP) method. We introduce the MP modes and present their informative spectral structure. We show theoretically that these modes can be divided into signal and noise modes, where the signal modes exhibit a ...
