Joint diagonalization of several correlation matrices is a powerful tool for blind signal separation. The paper addresses the blind signal separation problem for the case where the source signals are ...

It is well known that a set of non-defect matrices can be simultaneously diagonalized if and only if the matrices commute. In the case of non-commuting matrices, the best that can be achieved is ...

KEYWORDS: Tridiagonal Matrices; LU Factorization; Linear Systems; DETGTRI Algorithm; Thomas Algorithm JOURNAL NAME: Applied Mathematics, Vol.3 No.4, April 27, 2012 ABSTRACT: The current paper is ...

Some applications to the Ricci flow of left-invariant metrics on Lie groups concerning diagonalization are also given. This monthly journal, begun in 1950, is devoted entirely to research in pure and ...

Improve this page Add a description, image, and links to the exact-diagonalization topic page so that developers can more easily learn about it.

A very common problem in science is the numerical diagonalization of symmetric or hermitian 3x3 matrices. Since standard black box packages may be very inefficient if the number of matrices is large, ...

What is the expected behavior? When taking the matrix exponential of an Hermitean matrix M (for example to compute the time evolution operator from the Hamiltonian of a closed system) it is sometimes ...
