WebThis is a C++ Program to perform LU Decomposition of any matrix. In numerical analysis, LU decomposition (where ‘LU’ stands for ‘Lower Upper’, and also called LU factorization) factors a matrix as the product of a lower triangular matrix and an upper triangular matrix. The product sometimes includes a permutation matrix as well. my nano magic cloth https://gpfcampground.com

WebFor example, if you have a lower-triangular matrix L, and you see an expression like L − 1 y, you should almost never actually compute L − 1 and then multiply it by y. Instead, you would solve L x = y by forward-substitution, obtaining x = L − 1 y.
