Line 2: :Replied on [[User talk:TheFlyingPengwyn]]. -- [[User:Jitse Niesen\|Jitse Niesen]] 16:01, 30 Mar 2005 (UTC) == Inverses/products of triangular matrices == The article clearly states that products of upper triangular matrices are upper triangular, but it doesn't make the similar (and also true) claim about lower triangular matrices. Further, I only vaguely get the impression that the inverses of upper/lower triangular matrices remain upper/lower triangular. We should probably state these properties more directly, and perhaps clean up the article in general. --[[User:Rriegs\|Rriegs]] 04:11, 5 May 2007 (UTC)
