[cstex] Obdelnikova blokova matice s oznacenim dimenzi bloku

[Ladislav Bitto]

Zdravim,

aj ked Vam uz odpovedali, skusil som to jednoducho poskladat. Zvisle to 
islo jednoducho roztahovat, ale vodorovne iba pomocou jednoducheho makra.
Tu je kod:
\begin{document}\unitlength1.0cm 
\def\u#1#2{\begin{picture}(0,0)
        \put(0,-.2){\makebox(0,0)[c]{$\underbrace{\hspace{#1mm}}$}}
                \put(0,-0.5){\makebox(0,0)[c]{$#2$}}\end{picture}}
\begin{displaymath}
\arraycolsep3mm
\left(
  \begin{array}{cc|cc}
a& b& c& d\\
11& 22& 33& 444abcd\\
11& 22& 33& 444abcd\\
11& 22& 33& 444abcd\\
a& b& c& d\\
11& 22& 33& 444\\\hline
a& b& c& d\\
11& 22& 33& 444\\
a& b& c& d\\
11& 22& 33& 444123\\[-5mm] 
\multicolumn{2}{c}{\u{18}{a}}& 
\multicolumn{2}{c}{\u{28}{b}}
    \end{array}
\right)\hspace{-9mm}
  \begin{array}{l}
  \left.\begin{array}{l} \\ \\ \\ \\ \\ \\\end{array}\right\}p\\
  \left.\begin{array}{l} \\ \\ \\ \\\end{array}\right\}q
    \end{array}
\end{displaymath}
\end{document}

Mozno v tom blkarray to pojde tiez a jednoduchsie - to vsak musite asi 
prestudovat.
