A fully parallel method for tridiagonal eigenvalue problem

International Journal of Mathematics and Mathematical Sciences, 1994
In this paper, a fully parallel method for finding all eigenvalues of a real matrix pencil (A,B) is given, where A and B are real symmetric tridiagonal and B is positive definite. The method is based on the homotopy continuation coupled with the strategy

Finding Zeros of Analytic Functions and Local Eigenvalue Analysis Using Contour Integral Method in Examples

Advances in Electrical and Electronic Engineering, 2017
A numerical method for computing zeros of analytic complex functions is presented. It relies on Cauchy's residue theorem and the method of Newton's identities, which translates the problem to finding zeros of a polynomial.

Transparent Boundary Conditions for Finite Element Method-Based Parabolic Equation [PDF]

Journal of Electromagnetic Engineering and Science
In this letter, we propose a novel transparent boundary condition (TBC) for finite element method-based parabolic equation (PE) analysis. Conventional PE analysis uses a Hamming window, etc., adding an extra region to suppress non-physical reflected ...

Beamspace matrix pencil method for direction of arrival estimation

IEICE Electronics Express, 2009
In this paper, we propose DFT Beamspace Matrix pencil (BMP) method for direction of arrival estimation (DOA). The DFT beamspace approach has the advantage of reduced computational complexity due to converting complex computations (in Matrix Pencil method) into real ones along with the inherent ability to operate in a reduced beam-space in situations ...

Musical signal spectrum analysis with the matrix pencil method [PDF]

The Journal of the Acoustical Society of America, 1994
The matrix pencil spectrum analysis method provides an interesting alternative to classical Fourier analysis. The method is based on the assumption that the signal can be represented as a sum of exponentially damped sinusoids whose parameters (frequency, damping factor, amplitude and phase) are estimated by a matrix-based algorithm.
