I did not use LaTeX's picture environment for many years and I did not
use TikZ/pgf before, hence the following code is very ugly:


    \put(0,-10){\tikz\draw[->] (0mm,0mm) -- (14mm,-12mm);}

    \southeastarrow a & \southeastarrow b & c \\
    d & e & f \\
    g & h & i \\


You will certainly find a better solution if you read the manuals more
carefully than I did.  The TikZ/pgf manual is called pgfmanual.pgf.


Instead of TikZ/pgf you can also try \vector from LaTeX's picture
environment, but you should \usepackage{pict2e} which allows lines and
vectors to have arbitrary slopes.

You can also look into the XY-pic documentation, though I did not see
anything in the examples which is close to your problem and XY-pic
makes heavy use of special fonts while TikZ/pgf and pict2e can draw
straight lines with arbitrary slopes.

Even if you don't decide to use TikZ/pgf it doesn't hurt to browse the
manual.  It makes as much fun as reading Hans' MataFun documentation.

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
