    ILU preconditioning based on the FAPINV algorithm
    (2015) Salkuyeh, Davod Khojasteh; Rafiei, Amin; Roohani, Hadi
    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.
