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 wrapped CHOLMOD to provide a
sparse Cholesky decomposition: https://github.com/njsmith/scikits-sparse
This scikit isn't in Sage. However, you can install it into Sage using
these instructions:
http://packages.python.org/scikits.sparse/overview.html#introduction.
You could then use it like this:
http://packages.python.org/scikits.sparse/cholmod.html
Thanks,
