title: Perturbation bounds for triangular and full rank factorizations
zbMATH Open document ID: 1087.65023
publication date: 2006-02-16T00:00:00Z
review text: The author describes sharper perturbation bounds for LU and LDU factorizations which keep nonsingularity and existence of the decompositions. Exact expressions for the perturbation of the triangular factors are derived, which lead to improved componentwise upper bounds.
