About LU factorization

[DrD]

Found on the internet:

"LU factorization (when it exists) is not unique. If L has 1's on it's diagonal, then it is called a Doolittle factorization. If U has 1's on its diagonal, then it is called a Crout factorization. When L=Ut or U=Lt, it is called a Cholesky decomposition. "
