Phil Steitz resolved MATH-624. ------------------------------ Resolution: Fixed Patch applied in r1156968 with one change: s/MathRuntimeException.CreateXxx/new Xxx throughout. The former usage is deprecated. Thanks for the patch! > Need a method to solve upper and lower triangular systems > --------------------------------------------------------- > > Key: MATH-624 > URL: https://issues.apache.org/jira/browse/MATH-624 > Project: Commons Math > Issue Type: New Feature > Affects Versions: 3.0 > Environment: Java > Reporter: greg sterijevski > Assignee: Phil Steitz > Labels: Backsolve, Forwardsolve, LowerTriangular, UpperTriangular > Fix For: 3.0 > > Attachments: upperlowermethods, upperlowertests > > Original Estimate: 0h > Remaining Estimate: 0h > > I have run into a need to solve triangular systems. While (as Phil and Ted > point out) I could use the LU and QR decompositions, it seems cleaner to have > a couple of static functions which do this. I am including a patch to provide > an implementation and the tests. -- This message is automatically generated by JIRA. For more information on JIRA, see: http://www.atlassian.com/software/jira
