[Blindmath] Format for matrices

[Birkir R. Gunnarsson]

While MathML is definitely the way to go .. because that's where we
need to get, I've seen the matrix rows separated by a vertical bar |
(although it should be noted in the text prior to the matrix that this
is the way it is displayed).
Just an idea.
Cheers
