In numerical analysis, a field within mathematics, an incomplete LU factorization of a matrix is an sparse approximation of the LU factorization. Incomplete LU factorization is often used as a preconditioner.
Famous quotes containing the word incomplete:
“I dont think there is anything on earth more wonderful than those wistful incomplete friendships one makes now and then in an hours talk. You never see the people again, but the lingering sense of their presence in the world is like the glow of an unseen city at nightmakes you feel the teemingness of it all.”
—John Dos Passos (18961970)
