since I'm missing the ability to pass some kind of "format"-string to the
gmatrix environment of the
gauss package, and I learnt that this is not possible with redefining some environemnts used by the
gauss package (see gauss package set formatting (like the option for the array env)), I finally came to the point, when I decided to emulate some parts of the behaviour of the
gauss package to be more flexible.
I just wanted to ask you if there is some way to attach tikz arrows onto elements of the
array environment (and thus the pmatrix environment of the
amsmath package) or if the only way to do something like this is by setting the whole array/matrix within tikz?
(If maybe someone has already done this (then I'd be glad if this one would share ;) ))
