Version: 3.3 (current stable)
Eigen::LDLT has an API vectorD from which it is easy to obtain the log determinant of the Cholesky factor. Eigen::CholmodDecomposition offers no similar API.
I found an implementation in python, https://github.com/njsmith/scikits-sparse/blob/master/scikits/sparse/cholmod.pyx (search for "def D(self)").
I plan translate this into C++. Once I get it working, I would be happy to contribute it. Would this be a welcome addition to Eigen?
