View MATLAB Command. Compute the LU factorization of a matrix and examine the resulting factors. LU factorization is a way of decomposing a matrix A into an upper triangular matrix U, a lower triangular matrix L, and a permutation matrix P such that PA = LU.
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. MATLAB Central contributions by Lu. Publish your first comment or rating. Awarded to Lu on 09 Oct 2019 × 6.9.3. MATLAB Examples of LU¶ First, we ask MATLAB to just compute and . We can see that is not lower triangular as we think it should be.

The following matlab project contains the source code and matlab examples used for lu
The LU decomposition is introduced as used to find the determinant of a matrix. Prerequisites. Elementary row operations. Rudimentary understanding of the
where L is a lower triangular matrix and U is an upper triangular matrix. In Matlab compute using [L,U]=lu(S).

That is because MATLAB wanted to do row exchanges, but we didn’t let it, so it modified its algorithm. support.lth.se nedlagd.
