WebLU Decomposition. Row 1. Row 2. Row 3. Submit. Added May 29, 2024 by vik_31415 in Mathematics. WebThe LDV factorization. If a matrix has a unique LU factorization, it has a unique LDV factorization, where D is a diagonal matrix, L is a unit lower triangular matrix, and V is a unit upper triangular matrix. This can be seen immediately since in this case DV = U and so D is the matrix whose diagonal consists of U(1;1) through U(n;n), and V = D 1U.
