Follow-up Comment #12, bug #55564 (project octave): @Mike: Given that the inaccuracies of GESDD's results can be arbitrarily bad, I'd personally be wary to add any documentation encouraging users to try it, even if speed is valued more than accuracy. If anything, until this is better resolved on the LAPACK side, I think it would be prudent to warn users that using GESDD could be trading off *all* accuracy for speed! _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?55564> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
