Yesterday (Dec 2012) I've released version 0.3.0. So, it's mainteined quite active. Try to look at it.<br /><br />BTW, It supports 2D-array based dense matrices as well as 1D-array based (and also sparse implemnetions).Vladimir Kostyukovhttps://www.blogger.com/profile/07538486451812783386noreply@blogger.comtag:blogger.com,1999:blog-14415229.post-59826301538753641472010-02-12T20:25:18.880+01:002010-02-12T20:25:18.880+01:00Parallel Colt (http://sites.google.com/site/piotrw...Parallel Colt (http://sites.google.com/site/piotrwendykier/software/parallelcolt) is being actively maintained, even tho the original, non-multithread oriented Colt no longer is.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-14415229.post-19861678373305157252009-12-04T12:23:40.462+01:002009-12-04T12:23:40.462+01:00ojAlgo has been on SourceForge since early 2003 an...<a href="http://ojalgo.org" rel="nofollow">ojAlgo</a> has been on SourceForge since early 2003 and has been continuously worked on since then.<br /><br />Even if I, the 1-man, abandon the project the (open) source code is still there.<br /><br />Other people are welcome to contribute to the project, but so far no one has. It seems people would rather build their own. I believe I can find around 30 java linear algebra libraries (most of which are incomplete, buggy and/or slow).Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-14415229.post-36352569498765224212009-11-26T12:27:05.044+01:002009-11-26T12:27:05.044+01:00Jama is good but is also not very active (1.0 in 1...Jama is good but is also not very active (1.0 in 1998, minor fixes in 2003 and 2005, current release is 1.02).
