ILU (ILUPreconditioner) — Incomplete LU-factorization
ILUPreconditioner is a Preconditioner that uses Incomplete
LU-factorization to speed up the convergence of an iterative matrix method. It
usually works quite well. It is applicable to symmetric and
ILUPreconditioner uses the
CompRow_ILUPreconditioner from SparseLink++.
