Witryna31 sty 1998 · Abstract: Szego's (1984) theorem states that the asymptotic behavior of the eigenvalues of a Hermitian Toeplitz matrix is linked to the Fourier transform of its entries. This result was later extended to block Toeplitz matrices, i.e., covariance matrices of multivariate stationary processes. The present work gives a new proof of … WitrynaYou would only need a special algorithm for a matrix too large to handle by the usual methods. On the other hand, eigenvalues of large Toeplitz matrices can be numerically unstable, see e.g. Eigenvalues and Pseudo Eigenvalues of Toeplitz Matrices (Lothar Reichel, Lloyd N. Trefethen).
WitrynaWe study the inverses of block Toeplitz matrices based on the analysis of the block cyclic displacement. New formulas for the inverses of block Toeplitz matrices are proposed. We show that the inverses of block Toeplitz matrices can be decomposed as a sum of products of block circulant matrices. In the scalar case, the inverse … http://ramanujan.math.trinity.edu/wtrench/research/papers/TRENCH_RP_84.PDF
WitrynaSimilarly, given suitable decay, large but finite Hermitian Toeplitz matrices have approximately sinusoidal eigenvectors. I can look into details about the convergence … WitrynaWe consider the solutions of Hermitian positive definite Toeplitz-plus-diagonal systems $(T+D)x=b$, where T is a Toeplitz matrix and D is diagonal and positive. However, unlike the case of Toeplitz systems, no fast direct solvers have been developed for solving them. In this paper, we employ the preconditioned conjugate gradient method …
