Description Christoph Hertzberg 2013-08-19 12:58:28 UTC 
In bug 646 an issue was reported, that FullPivHouseholderQR (sometimes?) gives wrong results for typical least-squares like problems.
This is not covered in our testsuite at the moment.
Furthermore, test cases of different QR decompositions could at least partially be shared.
