I guess, this: http://trac.sagemath.org/sage_trac/ticket/7723 "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.
