\section{Introduction}
This paper is described how to use the {\sf nm.cls} class file for
publication in the {\it Numerical Mathematics: Theory, Methods and
Applications}. The {\sf nm.cls} class file preserves much of the
standard \LaTeXe \ interface so that authors can easily convert
their standard \LaTeXe \ {\sf article} style files to the {\sf nm}
style.

\section{Preparation of manuscript}
The Title Page should contain the article title, authors' names and
complete affiliations (including e-mail address). The Abstract
should provide a brief summary of the main findings of the paper.

References should be cited in the text by a number in square
brackets. Literature cited should appear on a separate page at the
end of the article and should be styled and punctuated using
standard abbreviations for journals (see Chemical Abstracts Service
Source Index, 1989). For unpublished lectures of symposia, include
title of paper, name of sponsoring society in full, and date. Give
titles of unpublished reports with "(unpublished)" following the
reference. Only articles that have been published or are in press
should be included in the references. Unpublished results or
personal communications should be cited as such in the text. Please
note the sample at the end of this paper.

Equations should be typewritten whenever possible and the number
placed in parentheses at the right margin. Reference to equations
should use the form "Eq.~(1.1)" or simply "(1.1)." Superscripts and
subscripts should be typed or handwritten clearly above and below
the line, respectively.


Figures should be in a finished form suitable for publication. Number figures consecutively with Arabic numerals.
Lettering on drawings should be of professional quality or generated by high-resolution computer graphics and
must be large enough to withstand appropriate reduction for publication.

\section{Header information}
The heading for any file using {\sf nm.cls} is like this;
\begin{verbatim}

\section{Some remarks}
\subsection{Mathematics}
{\sf nm.cls} makes the full functionality of \AmS\TeX \ available. We encourage
the use of the {\sf align}, {\sf gather} and {\sf multine} environments for displayed
mathematics.

\subsection{Cross-referencing}
The use of the \LaTeX cross-reference system for figures, tables, equations
and citations is encouraged.
