Four short stories about Toeplitz matrix calculations
, 2002 The stories told in this paper are dealing with the solution of finite, infinite, and biinfinite Toeplitz-type systems. A crucial role plays the off-diagonal decay behavior of Toeplitz matrices and their inverses. Classical results of Gelfand et al.

Eigenvalues of a Hessenberg-Toeplitz matrix
, 2019 Una matriz de Hessenberg Toeplitz es un tipo especial de matriz cuadrada que es “casi” triangular, estás matriz tiene ceros en las entradas sobre la primera superdiagonal, cada diagonal descendente de derecha a izquierda es constante y las entradas son coeficientes de Fourier de una función diferenciable definida en los complejos, esta función es ...

Toeplitz preconditioners for Hermitian Toeplitz systems
, 1993 We propose a new type of preconditioners for Hermitian positive definite Toeplitz systems Anx = b where An are assumed to be generated by functions f that are positive and 2π-periodic.

A Note On the Rank of the Optimal Matrix in Symmetric Toeplitz Matrix Completion Problem
, 2019 We consider the symmetric Toeplitz matrix completion problem, whose matrix under consideration possesses specific row and column structures. This problem, which has wide application in diverse areas, is well-known to be computationally NP-hard. This note

Structured low-rank approximation with missing data
The approach of SIAM J. Matrix Anal. Appl., 26(4):1083--1099 for solving structured total least squares problems is generalized to weighted structured low-rank approximation with missing data. The method proposed is based on elimination of the correction
