i think you have to let latex create the matrix first, then "overpaint" with tikz nodes, something like Alain Matthes' example:
http://www.texample.net/tikz/examples/m ... terminant/
(therefore use tikz matrix environment)

Code: Select all
\setlength{\oddsidemargin}{...}
\setlength{\evensidemargin}{...}
\usepackage
not \userpackage
. See the manual for closer description of the usage of NEW: TikZ book now 40% off at Amazon.com for a short time.
