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:
“Someone once asked me why women don’t gamble as much as men do, and I gave the common-sensical reply that we don’t have as much money. That was a true but incomplete answer. In fact, women’s total instinct for gambling is satisfied by marriage.”
—Gloria Steinem (b. 1934)
