Style

??=[entries.style] As mentioned above, the entries of a diagram are set in math mode in text style. You may change this by redefinining the macro ||, and the label style by redefining ||. We can combine this with the above to get `small diagrams', , typing
\begin{code}
$\left(
\spreaddiagramrows{-1.2pc}
\spreaddiagramcolumns{-1.2pc}
...
...{a} & B \dto^{b} \\
A'\uto^{a'} & B'\lto_{b'}
\enddiagram
\right)$
\end{code}
in a paragraph will typeset ``''.

You can even abandon the use of math mode entirely: the command || will change the format of entries to plain text.

With the "v3" matrix command the style and shape of individual entries can be changed.
