I think it's fine although I do have one fairly minor nitpick. I'd rather the
top and bottom of the large 'brackets' be done using / and \ as follows

\ 0 0 0 1 /

to avoid confusion with determinates which typically use the straight lines.

Works for me.

Hey, could you perhaps toss in the word "homogeneous" when describing that

Have fun,

Don
