Look, I said it was a 45-degree matrix, but I guess you chose to ignore
that.  Fine, use the numbers any way you want to.

}	I forgot to ask for a 16x16 matrix as well, don't suppose you
}have one do you?

The one I posted was a 16x16, order 8 matrix.  You get the other half
by replicating the half I posted, shifted by 8.

Are you getting the idea yet that you quite literally don't know what
you are talking about?  Perhaps you should stop posting 50-line followups
with 10 lines of new text, until you have at least sniffed a copy of
Ulichney's book?

}	Does anyone know if I can contact the MIT Press directly to order
}the book?

Your local bookstore is probably real good at ordering books.
