Line 199: </math> Instead of refactorizing {{math\|'''''B'''''}}, usually an [[LU factorization]] is directly updated after each pivot operation, for which purpose there exist several strategies such as the Forrest-Tomlin and Bartels−Golub method. However, the amount of data representing the updates as well as numerical errors builds up over time and makes periodic refactorization necessary.{{sfn\|Morgan\|1997\|loc=§2}}{{sfn\|Nocedal\|Wright\|2006\|p=372\|loc=§13.4}} ==Notes and references==
