WebThis de nition allows us to indicate when a matrix has an LU factorization: Theorem 3. Existence Let A2Cm n and m nhave linearly independent columns. Then Ahas a unique LU factorization if and only if all its principle leading submatrices are nonsingular. The proof of this theorem is a bit involved and can be found in Section 4. 2 LU Factorization WebNot to be confused with matrix factorization of a polynomial. In the mathematical discipline of linear algebra, a matrix decomposition or matrix factorization is a factorization of a matrix into a product of matrices. There are many different matrix decompositions; each finds use among a particular class of problems. safezone offshore training

WebSep 15, 2015 · Those can be expressed as multiplying $\bf A$ by a series of elementary matrices. The product of those should be lower triangular, so its inverse, name it $\bf L$, satisfies $\bf A=LU$. For the $LU$ decomposition, you need $\bf L$ to be unitriangular, i.e. have 1 on the diagonal. WebDec 2, 2011 · An invertible matrix admits an LU factorization if and only if all its leading principal minors are non-zero. The factorization is unique if we require that the diagonal of L (or U) consist of ones. The matrix has a unique LDU factorization under the same conditions.
