I want to see How to reduce the size of a matrix ?
I have this code:
\begin{center}
\[
\begin{blockarray}{cccccc}
{\{1\}\{2\}\{3\}} & {\{1,2\}\{3\}} & {\{1,3\}\{2\}} & {\{1\}\{2,3\}} & {\{1,2,3\}} \\
\begin{block}{(ccccc)c}
1 & 1 & 1 & 1 & 1 & {\{1\}\{2\}\{3\}} \\
0 & 1 & 0 & 0 & 1 & {\{1,2\}\{3\}} \\
0 & 0 & 1 & 0 & 1 & {\{1,3\}\{2\}} \\
0 & 0 & 0 & 1 & 1 & {\{1\}\{2,3\}} \\
0 & 0 & 0 & 0 & 1 & {\{1,2,3\}} \\
\end{block}
\end{blockarray}
\]
\end{center}
Best Answer
You could go
To reduce the size of all math or
To reduce it all in a different way
Or if you want to maintain the font size you need to experiment with reducing inter-column space (
\tabcolsep
)
