\begin{document}

\maketitle

\noindent
defines an array/matrix-type environment for subfigures and
subtables of the form,
%
\begin{lstlisting}
\begin{subfigmatrix}{NC}
  \subfigure[]{..}
   ...
\end{subfigmatrix}
\end{lstlisting}
%
where \meta{NC} is the number of subfigures per row (i.\,e.,\ the
number of columns).  the subfigures are ordered from
left-to-right, then top-to-bottom.

the environment is used within a float environment such as
\env{figure} or \env{table}.  each subfigure should have a variable width
tied to the local \cmd{\linewidth} value so each can be shrunk or
expanded to accomate the requested layout.

The environment does not require ``square'' matrices since it
only works on a row-by-row basis; thus you could have a $2 \times 4$,
a $1 \times 3$, or a $4 \times 2$ if you so choose.  if you neglect to give
it a full row, such as the case of a $3 \times 3$ matrix with only
8~elements, it simply fills the rows from left to right until
it runs out of elements.


\section{further example:}

if you wanted to create a figure with four subfigures in a tiled
or matrix format of $2 \times 2$, the following would suffice,
%
\begin{lstlisting}
\begin{figure}
  \begin{subfigmatrix}{2}
    \subfigure[]{...}
    \subfigure[]{...}
    \subfigure[]{...}
    \subfigure[]{...}
  \end{subfigmatrix}
  \caption{Example.}
  \label{f:eg}
\end{figure}
\end{lstlisting}
%
the result would look similar to the following,
%
\begin{quote}
  \begin{tabular}{@{\quad}c@{\quad}c@{\quad}}
    [subfig] &amp; [subfig] \\
    (a)      &amp; (b)      \\[2ex]
    [subfig] &amp; [subfig] \\
    (c)      &amp; (d)      \\[2ex]
    \multicolumn{2}{c}{Figure 1: Example.}
  \end{tabular}
\end{quote}


\section{notes:}

comments, bugs, fixes can be sent to \mail{w.l.kleb@larc.nasa.gov}.
what becomes of them is another story. ;)

each subfigure is placed within a \env{minipage} of the proper width
to fit \meta{NC} subfigures within the current float's \cmd{\linewidth},
accounting for $2 \times \cmd{\tabcolsep}$'s worth of space between each
adjacent subfigure.

\cmd{\linewidth} is a fairly general length.  it is equal to
\cmd{\textwidth} for single-column formats, \cmd{\columnwidth} for multiple-%
column documents (and also single-column documents), or
according to a \cmd{\parbox} or \env{minipage} environment.

if you are using the \pkg{graphicx} package, the subfigure widths are
automatically set to the local \cmd{\linewidth}.

the separation between figures can be changed via the
\cmd{\sfmcolsep} variable, e.\,g.,
%
\begin{lstlisting}
\setlength{\sfmcolsep}{\hspace{0.2in}}
\end{lstlisting}
%
to set a ``hard'' inter-column spacing as opposed to the
default behavior of tying the inter-column spacing to the
documents tabular column spacing (\cmd{\tabcolsep}\}.


\section{to do:}

\begin{itemize}
\item transposed ordering: from top-to-bottom, then left-to-right.
\end{itemize}
