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:
“The real weakness of England lies, not in incomplete armaments or unfortified coasts, not in the poverty that creeps through sunless lanes, or the drunkenness that brawls in loathsome courts, but simply in the fact that her ideals are emotional and not intellectual.”
—Oscar Wilde (1854–1900)
