\section{Introduction}

The proceedings will contain the extended abstracts of
lectures presented during the \textsc{Seminar on Numerical
Analysis} (SNA). The papers in the range of 2 - 4 pages
should be written in Czech or English and prepared in the
\LaTeX2e system with the aid of \texttt{sna} document style,
see Fig.\,\ref{labfig}. Of course, the authors can use any of
standard packages, e.g. \texttt{amsmath}.

%% Example of including a figure
\begin{figure}[h]
 \begin{center}
  \begin{minipage}{50mm}
   \begin{verbatim}
    \documentclass{sna}
    \begin{document}
       Text ...
    \end{document}
   \end{verbatim}
  \end{minipage}
  \vspace{-8mm}
 \end{center}
 \caption{An example of an extended abstract source code.}
 \label{labfig}
\end{figure}

The authors are asked to use only standard packages and minimize number 
of own commands or environments. It saves our time and eliminates our 
eventual type-writting errors caused by modification of your text.


\section{Text modifications}

The \texttt{imet} document class arose from the \texttt{article}
style. Therefore, most of its original instruments can be
exploited to modify the text of paper:
\begin{itemize}
 \item For \textit{the text sectioning}, the authors can use
       standard commands \texttt{$\mathtt{\backslash}$section},
       \texttt{$\mathtt{\backslash}$subsection}, etc. or their
       equivalent unnumbered forms \texttt{$\mathtt{\backslash}$section*},
       \texttt{$\mathtt{\backslash}$subsection*}, etc.
 \item Also \textit{mathematical formulae} can be written
       according to common standards as well as their references,
       e.g.\,(\ref{linsys}).

       \begin{equation}
        \label{linsys}
        A u = f \, , \qquad u, f \in R^n
       \end{equation}

 \item The authors can include \textit{figures and tables} into their
       texts, e.g. see Fig.\,\ref{labfig} and Tab.\,\ref{labtab}. The
       figures should be stored into standard graphic (JPG, PNG, BMP,
       \dots) or PDF files and included by tools of \texttt{graphicx}
       package into the text. The authors are encouraged not to use
       obsolete EPS files. The descriptions should be located bellow
       the figures and above the tables.

       \begin{table}[h]
        \caption{An example of a table.}
        \label{labtab}
        \begin{center}
         \begin{tabular}{|c|c|}
          \hline
          \textbf{Computer} & \textbf{Memory} \\
          \hline
           SUN HPC & shared      \\
           IBM SP  & distributed \\
          \hline
         \end{tabular}
        \end{center}
       \end{table}

 \item It is possible to use \textit{references} to the bibliography,
       e.g. \cite{t03, fh04}. The form of the bibliography is presented
       at the end of this paper.
\end{itemize}
