Title: Approximate inverse preconditioning of iterative methods for nonsymmetric linear systems

Abstract

A method for computing an incomplete factorization of the inverse of a nonsymmetric matrix A is presented. The resulting factorized sparse approximate inverse is used as a preconditioner in the iterative solution of Ax = b by Krylov subspace methods.
