I guess, this:

"I have not idea when I can get back to this at the moment. Basically
what has happened is that I bit the bullet and implemented my own
numerical matrix class hierarchy which is usable without Sage (but
loosely modeled after it). That ended up giving me the results I
needed much faster...
The long-term goal is to perhaps try to merge this back into Sage,
however as there's no real benefit for my own work in doing that I
don't really know if or when.
(Anyone who finds this ticket because they need this functionality are
welcome to send me an email and check the status.)"
Eventually I'm gonna need sparse matrices to play well with cvxopt.
Just a thought. I've not looked at this thread in any detail, but in some ways
going along with the MATLAB approach might be best. MATLAB has become pretty
popular at numerical stuff (far more than Mathematica). So many users might know
it better. There is also an Octave interface to Sage - Octave is basically a
MATLAB clone.
BTW, I do *not* know MATLAB much myself, so can't say how it handles things. But
perhaps some do. MATLAB is quite popular in engineering, though I have tended to
avoid it as I knew Mathematica first.
