چکیده

In this paper, we consider some inverse singular value problems for Toeplitz-related matrices. We construct a Toeplitz-plus-Hankel matrix from prescribed singular values including a zero singular value. Then we find a solution to the inverse singular value problem for Toeplitz matrices which have double singular values including a double zero singular value.

Sequential and Parallel Algorithms for the Inverse Toeplitz Singular Value Problem

When the Inverse Additive Singular Value Problem (IASVP) involves Toeplitz–type matrices it is possible to exploit this special structure to reduce the execution time. In this paper, we present two iterative local and global convergent algorithms (MIIIT and LPT) to solve efficiently the IASVP when the matrix is Toeplitz (IASVPT). As it will be shown, it can be achieved an asymptotic complexity ...

On group inverse of singular Toeplitz matrices

In this paper we show that the group inverse of a real singular Toeplitz matrix can be represented as the sum of products of lower and upper triangular Toeplitz matrices. Such a matrix representation generalizes “Gohberg–Semencul formula” in the literature. © 2004 Elsevier Inc. All rights reserved. AMS classification: 15A09; 65F20

TR-2002002: Can We Optimize Toeplitz/Hankel Computations? II. Singular Toeplitz/Hankel-like Case

In Part I, under the bit operation cost model we achieved nearly optimal randomized solution of nonsingular Toeplitz/Hankel linear system of equations based on Hensel's lifting. In Part II, we extend these results to the singular Toeplitz/Hankel-like case based on the MBA divide-and conquer algorithm and its combination with Hensel's lifting. We specify randomization and estimate the error/fail...
