[texhax] matrices

[Philip G. Ratcliffe]

P.S. the "correct" LaTeX definition is (gleaned from latex.ltx - always
worth a look):

\def\matrix#1{\null\,\vcenter{\normalbaselines\m at th
    \ialign{\hfil$##$\hfil&&\quad\hfil$##$\hfil\crcr
      \mathstrut\crcr\noalign{\kern-\baselineskip}
      #1\crcr\mathstrut\crcr\noalign{\kern-\baselineskip}}}\,}

and with adjustable brackets (no prizes for this one):

\def\pmatrix#1{\left(\matrix{#1}\right)}

Still, the 'amsmath' packages are worth looking into for "power" math users.

Cheers,  Phil
