Matrix Factorization and LU Decomposition

Matrix factorization (decomposition) means expressing a matrix $A$ as a product of two or more matrices. In LU decomposition, $A = LU$ , where $L$ is lower triangular and $U$ is upper triangular. The Doolittle method fixes the diagonal of $L$ to be all 1's. It is used to solve $Ax=b$ efficiently: ...
