Hello,
I'm new to this list, and new to TeX hacking, though I've been using
LaTeX to typeset math for about 4 or 5 years. One thing that I haven't
been able to get satisfied with is the way one has to enter matrices,
viz.,
$\left ( \begin{array}{ccc}
a & b & c \\ d & e & f \\ g & h & i
\end{array} \right )$
I would like to compress all of this into a macro like
the following:
$\matrix{a & b & c \\ d & e & f \\ g & h & i}$
The trick is detecting the number of columns dynamically, since I'd like
the same macro to work in this setting too:
$\matrix{a & b \\ c & d \\ f & g}$
Is it possible to do something like this? And can anyone suggest a way
to get started on it? Maybe there is already something built-in that I
just don't know about, I'd love to hear about that too.
Joe
