      Description

      Now that we've upgraded Eigen, we can get the determinant of sparse matrices. This might be informative for debugging. It's worth checking how long that calculation takes before doing it regularly: if it's slow, we could make it a configurable option.

            I should have realized this earlier in the slack conversation, but you can't compute the determinant without doing the factorization first.
