Convergence of block iterative methods for linear systems arising in the numerical solution of Euler equations [PDF]
Numerische Mathematik, 1991 The authors discuss certain block matrices that are natural block- generalizations of \(Z\)-matrices and \(M\)-matrices and arise in the numerical solution of Euler equations in the area of computational fluid mechanics. They investigate the properties of such matrices and, in particular, give a proof for the convergence of block iterative methods for ...

ACM Transactions on Mathematical Software, 2009 Recent advances in multilevel LU factorizations and novel preprocessing techniques have led to an extremely large number of possibilities for preconditioning sparse, unsymmetric linear systems for solving with iterative methods. However, not all combinations work well for all systems, so making the right choices is essential for obtaining an efficient ...

Two Iterative Methods for Solving Linear Interval Systems
Applied Computational Intelligence and Soft Computing, 2018 Conjugate gradient is an iterative method that solves a linear system Ax=b, where A is a positive definite matrix. We present this new iterative method for solving linear interval systems Ãx̃=b̃, where à is a diagonally dominant interval matrix, as ...
