PA = LU Factorization with Pivoting
2015-9-25 · PA = LU Factorization with Pivoting . Background Definition (LU-Factorization). The nonsingular matrix A has an LU-factorization if it can be expressed as the product of a lower-triangular matrix L and an upper triangular matrix U: . When this is possible we say that A has an LU-decomposition. It turns out that this factorization (when it ...
