convert them to vectors first. And then you wind up transposing the
matrix twice, and then you have to convert everything back to vectors
and then back to algebra elements, dropping the zero vectors/elements
in the process. Sounds slow, right?

default implementation isn't much slower than the custom routine I
wrote. So, for now, let's delete it.
