%
% \section{Introduction}
% Sometimes two or more floats (figures or tables) belong together in a
% way you should not use different caption numbers for them. 
% With a subnumbering like that of the amsmath package for equations
% it is possible to point out the connection of the floats.
% This package provides two environments and four macros to achive
% subnumbering of floats.
% It is possible to change the caption labels.
%
% In case of problems or bugs please send an email to my address
% printed on the title page.
%
% \section{The user interface}
%
% To use this package place
% \begin{verbatim}
% \usepackage{subfloat}
% \end{verbatim}
% in the preamble of your document.
% No options are necessary.
%
% \changes{2.10}{2002/09/06}{Add counting of subfloats}%
% If you want to be able to count the number of subfloats with the
% same main number you have to add the package option |countmax|:
% \begin{verbatim}
% \usepackage[countmax]{subfloat}
% \end{verbatim}
% For more description to counting see section~\ref{sec:count}.
%
% \subsection{Environments}
% \DescribeEnv{subfigures}
% Put
% \begin{verbatim}
% \begin{subfigures}
% \end{subfigures}
% \end{verbatim}
% around the figures which belong together.
% By default, they get the same figure number with an increasing
% lowercase character added. 
% \DescribeEnv{subtables}
% In the same way you can put
% \begin{verbatim}
% \begin{subtables}
% \end{subtables}
% \end{verbatim}
% around tables. The macros for the environments have to be placed outside
% the picture or table environments.
%
% \subsection{Macros}
% \DescribeMacro{\subfiguresbegin}
% \DescribeMacro{\subfiguresend}
% Instead using of the environments it is possible to use adequate macros:
% \begin{verbatim}
% \subfiguresbegin
% \subfiguresend
% \end{verbatim}
% \DescribeMacro{\subtablesbegin}
% \DescribeMacro{\subtablesend}
% or
% \begin{verbatim}
% \subtablesbegin
% \subtablesend
% \end{verbatim}
%
% Put these macros in place of the environment macros. The macros are
% necessary to be able to nest subnumbered figures and tables.
%
% If you put labels inside the figure and table environments the subfloat
% label numberes are referenced. 
% If you want a reference to the common figure or table number place a 
% label right after the |\begin{subfigures}|, |\subfiguresbegin|, 
% |\begin{subtables}|, or |\subtablesbegin| command.
% 
% \section{Examples}
% \subsection{Using the environments}
%
% \DescribeEnv{subfigures}
% The code
% \begin{verbatim}
% \begin{subfigures}
% \label{fig:fig1a2}
% %
% \begin{figure}\centering
%   \fbox{fig. 1}
%   \caption{This is the first figure}\label{fig:fig1}
% \end{figure}
% %
% \begin{figure}\centering
%   \fbox{fig. 2}
%   \caption{This is the second figure}\label{fig:fig2}
% \end{figure}
% %
% \end{subfigures}
% \end{verbatim}
% produces the output of the figures~\ref{fig:fig1a2} 
% (figure~\ref{fig:fig1} and figure~\ref{fig:fig2}).
% References are made as usual with
% e.\,g. |\ref{fig:fig1}|.
% %
% \begin{subfigures}
% \label{fig:fig1a2}
% %
% \begin{figure}\centering
%   \fbox{fig. 1}
%   \caption{This is the first figure}\label{fig:fig1}
% \end{figure}
% %
% \begin{figure}\centering
%   \fbox{fig. 2}
%   \caption{This is the second figure}\label{fig:fig2}
% \end{figure}
% %
% \end{subfigures}
%
% \DescribeEnv{subtables}
% The output of the tables~\ref{tab:tab1} and \ref{tab:tab1} is
% generated similarly:
% \begin{verbatim}
% \begin{subtables}
% %
% \begin{table}\centering
%   \caption{This is the first table}\label{tab:tab1}
%   \begin{tabular}{l} \hline
%   table 1\\ \hline
%   \end{tabular}
% \end{table}
% %
% \begin{table}\centering
%   \caption{This is the second table}\label{tab:tab2}
%   \begin{tabular}{l} \hline
%   table 2\\ \hline
%   \end{tabular}
% \end{table}
% %
% \end{subtables}
% \end{verbatim}
% %
% \begin{subtables}
% %
% \begin{table}\centering
%   \caption{This is the first table}\label{tab:tab1}
%   \begin{tabular}{l} \hline
%   table 1\\ \hline
%   \end{tabular}
% \end{table}
% %
% \begin{table}\centering
%   \caption{This is the second table}\label{tab:tab2}
%   \begin{tabular}{l} \hline
%   table 2\\ \hline
%   \end{tabular}
% \end{table}
% %
% \end{subtables}
%
% The environment names |subfigures| and |subtables| were
% chosen to be similar to the |subequations| environment of the
% amsmath package. But what is to do when both environments have to be
% nested? This case is handled in the next section.
% 
% \subsection{Using the macros}
% \DescribeMacro{\subfiguresbegin}
% \DescribeMacro{\subfiguresend}
% \DescribeMacro{\subtablesbegin}
% \DescribeMacro{\subtablesend}
% The usage of the macros is shown in the example below:
% \begin{verbatim}
% \subfiguresbegin
% \begin{figure}
% [...]
% \begin{table}
% [...]
% \subtablesbegin
% \begin{table}
% [...]
% \begin{figure}
% [...]
% \subfiguresend
% \begin{figure}
% [...]

% With these macros it is possible to realise nested subnumbers of
% figures and tables. Even nested subnumbers of figures or tables and
% equations made with the subequations environment of the amsmath
% package are possible.
% 
% \section{Change the label format}
%
% The standard label format is the global float number followed by a
% lowercase alphanumerical subfloat number.
% This can be changed by redefining the commands |\thesubfloatfigure|
% and |\thesubfloattable|.
% Both define the whole float number including the main number. 
% The main number is referred by |\themainfigure| resp.\
% |\themaintable|. 
% The counters of the subfloats are |subfloatfigure| resp.\
% |subfloattable|.
% The default values are:
% \begin{verbatim}
% \newcommand*\thesubfloatfigure{\themainfigure\alph{subfloatfigure}}
% \newcommand*\thesubfloattable{\themaintable\alph{subfloattable}}
% \end{verbatim}
% If you want to print the subnumber of figures in brackets, you may
% define this:
% \begin{verbatim}
% \renewcommand*\thesubfloatfigure{\themainfigure(\alph{subfloatfigure})}
% \end{verbatim}
% If you want a sublabel in the format 1--1, 1--2, \dots\ you can
% get it by the following command sequence:
% \begin{verbatim}
% \renewcommand*\thesubfloatfigure{\themainfigure--\arabic{subfloatfigure}}
% \end{verbatim}
%
% Since it is done the same for tables this it not described again.
%
% \section{Count subfloats}%
% \label{sec:count}%
% \changes{2.10}{2002/09/06}{Add counting of subfloats}%
%
% If the package option |countmax| is used the package counts the
% number of all subfloats with the same main float number. This number
% is stored in the counters |subfloatfiguremax| resp.\
% |subfloattablemax| and can be used for changeing the labels, e.g.:
% \begin{verbatim}
% \renewcommand*\thesubfloatfigure{%
%     \themainfigure(\arabic{subfloatfigure}/\arabic{subfloatfiguremax})}
% \end{verbatim}
% \changes{2.13}{2002/12/16}{Remove generation of error message
%   because of incompatibility with tabularx}%
% If the package option is not set but |subfloatfiguremax| used an
% error messages is produced by \LaTeX. Normally there should be an
% error message of the following types:
% \begin{verbatim}
% ! Missing number, treated as zero.
% <to be read again> 
%                    \c@subfloatfiguremax 
% l.64        }
%              
% ? 
% \end{verbatim}
% or
% \begin{verbatim}
% ! Undefined control sequence.
% <write> ...abel{ressim2}{{I(b/\c@subfloattablemax 
%                                                   )}{\thepage }{Estimation o...
% l.105 \end{document}
%                     
% ? 
% \end{verbatim}
% There may be |\c@subfloatfiguremax| or |\c@subfloattablemax|.
% In a former version, |subfloat| has generated a nice error
% message. But unfortunately this code has been incompatible to
% |tabularx|.
%
% In order to get the numbers right \LaTeX\ has to be run twice or
% three times.\footnote{Internally, this is implemented using labels.
%   After the first \LaTeX\ run, the counter is zero end thus not
%   displayed for alpha or roman numbering.}
