چکیده
In this paper we formulate a theory of LU and Cholesky factorization of bi-infinite block Toeplitz matrices A = (Ai−j )i,j∈Zd indexed by i, j ∈ Zd and develop two numerical methods to compute such factorizations. © 2002 Elsevier Science Inc. All rights reserved.

متن کاملA Toeplitz algorithm for polynomial J-spectral factorization
A block Toeplitz algorithm is proposed to perform the J-spectral factorization of a para-Hermitian polynomial matrix. The input matrix can be singular or indefinite, and it can have zeros along the imaginary axis. The key assumption is that the finite zeros of the input polynomial matrix are given as input data. The algorithm is based on numerically reliable operations only, namely computation ...
متن کاملA Method for Generating Infinite Positive Self-adjoint Test Matrices and Riesz Bases
In this article we propose a method to easily generate infinite multi-index positive definite self-adjoint matrices as well as Riesz bases in suitable subspaces of L2(Rd). The method is then applied to obtain some classes of multi-index Toeplitz matrices which are bounded and strictly positive on 2(Zd). The condition number of some of these matrices is also computed.
