Laplace's method is, btw, one of the worst ways to compute determinants. It
is on a par with using Cramer's rule for solving linear systems.
Much better to do QR and take the product of the diagonal of the R matrix or
do the same with the diagonal matrix out of an SVD. Even LU decomposition
is better.
It is nice to have implementations like this and have people exercise the
matrix code, but nobody should actually be using these algorithms for
anything serious.
At first I was not sure to add it as there are no use cases yet, but
then I thought it's nice with some stuff in the trunk.
