Travis,

   Thanks for the response (you too Pearu!). I've got a
follow-up below.

What's the difference between using quotes and using brackets []
as Pearu suggested? BTW, I like the methods for computing the
transpose. Is something like A.shape a method or a property of
the mat class? (i.e. is computed when it's created or just when it's
needed)


Thanks!

Jeff
