Journal ArticleDOI
The Constrained Solutions of Two Matrix Equations
TL;DR: In this article, the authors studied the symmetric positive semidefinite solution of the matrix equation where A is a given real m×n matrix, B is a real m × p matrix, and C is a true m×m matric, with m, n, p positive integers.
Journal ArticleDOI
A class of modified block SSOR preconditioners for symmetric positive definite systems of linear equations
TL;DR: A class of modified block SSOR preconditioners is presented for solving symmetric positive definite systems of linear equations, which arise in the hierarchical basis finite element discretizations of the second order self‐adjoint elliptic boundary value problems.
Journal ArticleDOI
Regularized HSS iteration methods for saddle-point linear systems
Zhong-Zhi Bai,Michele Benzi +1 more
TL;DR: Numerical results on saddle-point linear systems arising from the discretization of a Stokes problem and of a distributed control problem show that good performance can be achieved when using inexact variants of the proposed preconditioners.
Journal ArticleDOI
On Preconditioned Iterative Methods for Burgers Equations
TL;DR: It is found that a combination of the Newton/fixed-point iteration with the preconditioned GMRES method is quite efficient for the Sinc-Galerkin discretization of the Burgers equations.
Journal ArticleDOI
Block and asynchronous two-stage methods for mildly nonlinear systems
TL;DR: Both synchronous and asynchronous versions of the asynchronous method when applied to linear systems are analyzed, and both pointwise and blockwise convergence theorems provided.
