No, no, I must have given the wrong impression, I'm still in the matrix
camp. My main complaint would have been absence of equivalents for ones,
zeros, etc., but it seems Travis has introduced numpy.matlib exactly for
that, which is great. Before that, I sometimes felt like a second-class
citizen because many people on the list argued that users should invent
their own workarounds (which btw I have done in the meantime, but that's
not the purpose of a ready-to-use matrix package, is it?).

Well if numpy.matlib does what I think it does there are no pressing
issues for me right now. Element-wise multiplication isn't that
important for me.
Of course I'll let you know as soon as something occurs to me ;-)
Thanks for offering,
Sven
