Some algorithms for solving special tridiagonal block Toeplitz linear systems
نویسنده
چکیده
This paper is focused on di1erent methods and algorithms for solving tridiagonal block Toeplitz systems of linear equations. We consider the El-Sayed method (Ph.D. Thesis, 1996) for such systems and propose several modi9cations that lead to di1erent algorithms, which we discuss in detail. Our algorithms are then compared with some classical techniques as far as implementation time is concerned, number of operations and storage. Comments and conclusions for computing e:ciency of the proposed new algorithms are given. Numerical experiments corroborating the theoretical results are also presented. c © 2003 Elsevier Science B.V. All rights reserved.

Convergence of Cg and Gmres on a Tridiagonal Toeplitz Linear System
The Conjugate Gradient method (CG), the Minimal Residual method (MINRES), or more generally, the Generalized Minimal Residual method (GMRES) are widely used to solve a linear system Ax = b. The choice of a method depends on A’s symmetry property and/or definiteness), and MINRES is really just a special case of GMRES. This paper establishes error bounds on and sometimes exact expressions for res...
متن کاملA Parallel Algorithm for Circulant Tridiagonal Linear Systems
In this paper, based upon the divide-and-conquer strategy, we propose a parallel algorithm for solving the circulant tridiagonal systems, which is simpler than the two previous algorithms proposed by Agui and Jimenez ( 1995) and Chung et al. ( 1995). Our algorithm can be easily generalized to solve the tridiagonal systems, the block-tridiagonal systems, and the circulant block-tridiagonal syste...
متن کاملA New Two-stage Iterative Method for Linear Systems and Its Application in Solving Poisson's Equation
In the current study we investigate the two-stage iterative method for solving linear systems. Our new results shows which splitting generates convergence fast in iterative methods. Finally, we solve the Poisson-Block tridiagonal matrix from Poisson's equation which arises in mechanical engineering and theoretical physics. Numerical computations are presented based on a particular linear system...
متن کاملThe spectral decomposition of near-Toeplitz tridiagonal matrices
Some properties of near-Toeplitz tridiagonal matrices with specific perturbations in the first and last main diagonal entries are considered. Applying the relation between the determinant and Chebyshev polynomial of the second kind, we first give the explicit expressions of determinant and characteristic polynomial, then eigenvalues are shown by finding the roots of the characteristic polynomia...
متن کاملStable Factorizations of Symmetric Tridiagonal and Triadic Matrices
We call a matrix triadic if it has no more than two nonzero off-diagonal elements in any column. A symmetric tridiagonal matrix is a special case. In this paper we consider LXLT factorizations of symmetric triadic matrices, where L is unit lower triangular and X is diagonal, block diagonal with 1×1 and 2×2 blocks, or the identity with L lower triangular. We prove that with diagonal pivoting, th...
