WebThere are three important matrix factorizations: LU, QR, and SVD. 1. LU factorization. A factorization of a matrix A in the form A = LU, where L is unit lower triangular and U is upper triangular, is called an LU factorization of A. An LU factorization of A exists if all of its leading principal minors are nonsingular.
WebA converse to existence I Theorem Suppose A 2Cn;n has an LU-factorization. If A is non-singular then the leading principal submatrices A k are nonsingular for k = 1;:::;n 1. I Proof: Suppose A is nonsingular with the LU-factorization A = LR. I Since A is nonsingular it follows that L and R are nonsingular. I By Lemma we have A k = L kR k.
