Ah, interesting! That's exactly the kind of stuff I was looking for,
although the lack of support for sparse arrays means
I wouldn't be able to use it for anything but toy problems: although
the vector of coordinates is dense, the other matrices involved in
this program (which are sized NxN where N is the vector size) must
be sparse.
