Multiple Matrix Reconstruction for Two-Dimensional Direction Estimation of Mixed Signals Without Eigen Decomposition

Abstract: In this paper, a novel method based on multiple matrix reconstruction without eigen decomposition is proposed for solving the problem of two-dimensional (2-D) direction-of-arrival (DOA) ...

Zhao, K. and Liu, Z.Y. (2023) Eigenvalue Embedding of Damped Vibroacoustic System with No-Spillover. SIAM Journal on Matrix Analysis and Applications, 44, 1189-1217.

ABSTRACT: In this paper, we consider the model updating problem of the undamped vibroacoustic system with no spill-over (MUP-UVA), which is to update the original system to a new system such that some ...

Here’s Why ‘The Matrix’ Is More Relevant Than Ever

One scene reflects the themes — A.I., fake news, transgender lives and Gen X — that make the film a classic. By Alissa Wilkinson Neo, the hero of “The Matrix,” is sure he lives in 1999. He has a green ...

Eigenvalue Decomposition of a Parahermitian Matrix: Extraction of Analytic Eigenvectors

Abstract: An analytic parahermitian matrix admits in almost all cases an eigenvalue decomposition (EVD) with analytic eigenvalues and eigenvectors. We have previously defined a discrete Fourier ...

Perplexing template deduction failure serialising a 3rd party type using base class

I know (and have checked with a basic code example) that if a serialisation is defined for a base class/struct, then derived classes can be serialised too without additional code (the derived classes ...

Regression: Eigenvalue of specific hermitian 4x4 matrix now piecewise instead of actual result

Back in sympy 1.5.1 days I ran some calculations where I needed to get the eigenvalues of a hermitian 4x4 matrix. Now I just tried running the calculations again with sympy 1.9 and they fail miserably ...
