Det følgende er et udklip fra en fil med en artikel skrevet i LaTeX. Den indeholder de fleste af eksemplerne der blev omtalt i foredraget.

(particle positions are determined using spot on three or four of
the images from the four cameras - whenever, following a particle
in time, a changes occur in which of the cameras were used to
calculate the particle position, we cut the track and relabel the
particle as a different one before and after the change)

In order to work around this problem Sawford has constructed a
stochastic model for Lagrangian velocity structure
functions~\cite{Sawford_on_Lagrangian_Reynolds_number}. In his
paper on the model he fixes the free parameters of the model using
results from direct numerical simulations of the Navier-Stokes
equations. In figure~\ref{figure:velocity structure function tops}
we compare a numerical solution for $C_0^*(R_{\lambda})$ with our
experimental results and with simulations by Yeung and Pope.

\caption{
The top values of the rescaled second order Lagrangian velocity
structure function for different data-sets. {\em Present} refers
to the six data-sets presented in this article, and {\em DNS}
refers to the four computer simulation based data-sets discussed
in~\cite{Lagrangian_statistics_from_DNS,Sawford_on_Lagrangian_Reynolds_number,lagrangian_pdf_methods}
The last four values were read of figure 10
in~\cite{lagrangian_pdf_methods}.

Programmet `bibtex` gør at man kan have en samlet liste med
alle de artikler og bøger man kan få brug for at referere til. Bibtex
trækker de henvisninger der er i et LaTeX-dokument ud og laver en
litteraturliste til dokumentet med lige netop de artikler.
Man indsætter en henvisning til en artikel med "cite":

Stikord til stikordsregistret:
converts the mechanical energy into heat. The part of this range of
length scales where energy spectrum shows power-law behaviour, is today
called the inertial range\index{inertial
range}\index{range!inertial}.
\begin{equation}
K \propto l^{\frac{4}{3}}
\end{equation}
You could also just write $K \propto l^{\frac{4}{3}}$.
\begin{eqnarray}
\langle\delta{v}_{\parallel}^2(r)\rangle
& = & C_K (\epsilon r)^{\frac{2}{3}}
\label{Equation:Kolmogorov 2nd order longitudinal structure function}
\\
\langle\delta{v}_{\perp}^2(r)\rangle
& = & \frac{4}{3} \langle\delta{v}_{\parallel}^2(r)\rangle

Jeg har bogen The LaTeX Companion
liggende på mit skrivebord.
Derudover er nyhedsgruppen <news://news.sslug.dk/sslug.dok>
et godt sted at stille spørgsmål om LaTeX.

Pakken "epsfig" tillader at man indsætter Postscript-filer
i sit LaTeX-dokument.
Æ, ø og å (og den slags) kan både skrives med koder i et 7-bit ISO-646-format:
von K\'{a}rm\'{a}n
og som almindelig 8-bit ISO-8859-1:
von Kármán
For de fleste dokumenttyper er det nødvendigt at indsætte følgende oppe i dokumenthovedet:
\usepackage[latin1]{inputenc}
\usepackage[danish]{babel}
\usepackage[T1]{fontenc}
(hvor "danish" selvfølgelig kan udskiftes med et andet
sprog efter behov), hvis der skal bruges ISO-8859-1.
