On eigenvalue variations of rayleigh quotient matrix pencils of a definite pencil

Linear Algebra and its Applications, 1994
The main purpose of this paper is to improve the result for the spectral norm cited by \textit{J. Sun} [Linear Algebra Appl. 139, 253-267 (1990; Zbl 0711.15009)]. Also, bounds in Frobenius norms and in general unitarily invariant norms are presented.

On the Equivalence of Two Singular Matrix Pencils [PDF]

Proceedings of the Edinburgh Mathematical Society, 1936
In a recent paper Turnbull, discussing a rational method for the reduction of a singular matrix pencil to canonical form, has shown how the lowest row, or column, minimal index may be determined directly without reducing the pencil to canonical form. It is the purpose of this note to show how all such indices may be determined, and at the same time to ...

Multi-Object Feature Extraction in Resonance Region Based on Short-Time Matrix Pencil Method

Remote Sensing
As 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 ...
