Re: [eigen] Using SparseLU to calculate the determinant.

[Desire NUENTSA <desire.nuentsa_wakam@xxxxxxxx>]

Hi,
Please, find a feature request at http://eigen.tuxfamily.org/bz/show_bug.cgi?id=588
with a patch to do that.
In my opinion, We should add a feature to balance the matrix before pushing the patch.

Hi,

Decided to email this since SparseLU is in 3.2.0-beta1. 

Currently, calculating the determinant of a sparse matrix can be achieved using the SparseCholesky module. Is there a plan to extend this functionality to the SparseLU module? Not sure how trivial this is since I have not looked into the specifics of the implementation and how the factorisation is stored.
