  Interesting: that's a direct product, which we hardly ever use.
  This supports my statement up-thread that while matrices in general
  are well known and commonly used, getting any two people to agree on
  the interface is difficult, because people use them so differently.

  That statement is not true of complex numbers, which pretty much
  everyone uses the same way.
