Matlab program for LU Factorization using Gaussian elimination without pivoting. function [L,A]=LU_factor(A,n) % LU factorization of an n by n matrix A % using Gauss elimination without pivoting % LU_factor.m % A is factored as A = L*U % Output: % L is lower triangular with the main diagonal part = 1s. LUD (LU Decomposition) 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. The following Matlab project contains the source code and Matlab examples used for lu decomposition. This program will obtain the LU decomposition for any square matrix.

LU decomposition. The LU decomposition of a matrix is the pair of matrices and such that: \({\bf A} = {\bf LU}\) is a lower-triangular matrix with all diagonal entries equal to 1; is an upper-triangular matrix. The properties of the LU decomposition are: The LU decomposition may not exist for a matrix . If the LU decomposition exists then it is unique.
