Dima,
I never work with CHOLMOD cvxopt directily, but if there is any thing that
I can do to help you to get sparse Cholesky implemented for non-exact
sparse Sage matrices just say.

+1. Always +1 to that question. :)

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.

far a way to make it more sane. It turns out that cvxopt has un
undocumented function to
extract the Cholesky factor directly.

OK, my previous reply didn't make much sense, so here is one that is
meaningful. In cvxopt (a standard Sage spkg) there is an interface to

Thanks all reply.
I really like to make a little improve to Sage can handle the sparse
matrix. Should I open a ticket?

Scipy had some interest in adding sparse cholesky [1], but it seems that
nothing came of it.
On the other hand, it would be cool if we wrapped something like CHOLMOD
[2] to compute sparse cholesky decompositions.
It looks like the scikits-sparse package

the error message is clear: there is no implementation for RDF matrices,
only for exact matrices.

the error message is clear: there is no implementation for RDF matrices,
only for exact matrices. So you can do this for QQ, for instance.
