Neither is LU factorization. I'd argue that since we actually include LU, it
would make sense to also include *a few* *important* linear algebra things
that can be implemented using LU with not much effort. For example, det, inv,
and a linear solve driver.
Any serious user of these things should be driven towards LAPACK and the
bindings, but for quick, oneoff stuff, the builtin versions should be just
fine.
Opinions?
