And the multiplication appeared to work, but gave the wrong answer. I don't remember this bug, but I can't duplicate it now on my system. If it wasn't a bug that was fixed in Octave, then I'd guess it was a BLAS bug? Octave just uses BLAS to perform these mutliplications. jwe -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
