WebAn n × n square matrix A = [a ij] is said to be a lower triangular matrix if and only if a ij = 0, for all i < j. This implies that all elements above the main diagonal of a square matrix are zero in a lower triangular matrix. A general notation of a lower triangular matrix is L = [l ij for i ≥ j, 0 for i < j]. An example of a lower ... WebApr 27, 2024 · How to transform a matrix into lower-triangular form using permutation matrix. Given a real n × n matrix A, all diagonal entries are 0, there are at most ( n − 1) non-zero entries in A, and if A ( i, j) is non-zero, A ( j, i) is 0. For example, a matrix A is. Webis a unit lower triangular matrix and U is an upper triangular matrix. Equation (2.7.2) is referred to as the LU factorization of A. It can be shown (Problem 29) that this LU factorization is unique. Example 2.7.7 Determine the LU factorization of the matrix A = 25 3 31−2 −12 1 .
