Abstract

A technique for computing an ILU preconditioner based on the factored approximate inverse (FAPINV) algorithm is presented.We show that this algorithm is well-defined for H-matrices.Moreover, when used in conjunction with Krylov-subspace-based iterative solvers such as the GMRES algorithm, results in reliable solvers.Numerical experiments on some test matrices are given to show the efficiency of the new ILU preconditioner.
