Hi, after a discussion here: https://groups.google.com/d/topic/cvxopt/xQ-lR9ESijg/discussion it turns out that there is enough CHOLMOD interface already in Sage, it's just not documented properly. Should I volunteer to get sparse Cholesky implemented for non-exact sparse Sage matrices, via this route?
