Introduction to Latex
A very quick look at typesetting
documents
Andrei Gurtov
(based on Troy D. Milner and Simon Cuce slides)

Introduction
 Essentially a Markup Language (like
HTML, XML and RTF)
 An extension to TeX system
 TeX written by Donald Knuth in 70´s

Latex vs. Word Processors
 High typeset quality
 Easy to include math formulas
 Source file format id not bounded to a
particular OS or platform
 Latex implementations exists for all
platforms (DOS, Windows, Unices,..)
 Latex is free

Latex vs. Word Processors
 De facto standard for scientific
publishing
 Very few bugs
 Good for large documents
 Can run even on 386 PC
 Not very easy to learn

Creating Latex Files
Your Latex File Your Bibtex File
Latex compile x3
Bibtex compile x2
Latex compile x3
Your Postscript File
Dvips compile x1

Latex File Structure
 Document Class
Predefined Formats (article, report, book,..).
 Packages used
Added Functionality (graphics, reference style,...).
 Main Body
Text and Bibliography References.

The Basics
 Document Class
documentclass[options]{class}
options = a4paper, 11pt, 12pt, 10pt, twocolumn,
landscape,...
class = article, report, book,...
 Packages
usepackage{package name}
epsfig = insert PS pictures into the
document
fancyhdr = easy definition of footer and
header

Body of Text
 Start with begin{document}
 End with end{document}
 Typesetting Text
– or newline and newpage
– Quotations
– Bold textbf{……………} or bf
– Italics emph{…………} or textit{………} or it
– Underline underline{…………} or ul

Body of Text cont…
 Including Multiple Files
– input{filename.tex}

Format
 Sections
– section{…} = 1. Latex is Great
– subsection{…} = 1.1 Why Latex is Great
– subsubsection{…} = 1.1.1 Reason One
– appendix - changes numbering scheme
– chapter{…} - To be used with book and report
document classes
 Titles, Authors and others
– title{…} author{…}
– footnote{…}

Format Contd.
 maketitle - Display Title and Author
 tableofcontents - generates TOC
 listoftables - generates LOT
 listoffigures - generates LOF
 Labels
– label{marker} - Marker in document.
– pageref{marker} - Displays page no. of marker.
– ref{marker} - Displays section location of marker.
 Itemise
– Use either enumerate, itemize or description.
– see handout for example.

Lists
 Source
– begin{itemize}
– item Apple
– item Orange
– end{itemize}
 Result
– Apple
– Orange

Lists
 Enumerate instead of itemize gives
a numbered list
 Lists can be recursive

Environment
 Something between
– begin{name}
– end{name}
 Many command, for example bf affect
the text until the end of environment
 Can be recursive
 Examples:
– itemize, center, abstract

Group
 Text between { and }
 Many commands work until the end of
the group
 Code
– put {one word bf in bold} here
 Result
– put one word in bold here

Alignment
 Environments center, flushleft,
flushright
 Example
– begin{flushright}
– Right aligned
– end{flushright}
 Result
Right aligned

Font size
tiny scriptsize footnotesize
small normalsize
large Large
LARGE huge
Huge

Example of Latex document
documentclass{article}
title{Simple Example}
author{Andrei Gurtov}
date{March 2000}
begin{document}
maketitle
Hello world!
end{document}

Tabular
 Columns
– begin{tabular}{|…|…|}
– end{tabular}
 Rows
– & - Split text into columns
– - End a row
– hline - Draw line under row
– e.g. 123123 & 34.00 hline
Two Columns
l = automatically adjust
size, left justify
r = automatically adjust
size, right justify
p = set size
e.g p{4.7cm}
c = centre text

Example of table
begin{tabular}{|l|r|c|} hline
Date & Price & Size hline
Yesterday & 5 & big hline
Today & 3 & small hline
end{tabular}
Date Price Size
Yesterday 5 Big
Today 3 Small

Floating Bodies
 Floating bodies can stop splitting of tables
and images over pages.
begin{figure}[options]
begin{table}[options]
 They will now appear in the LOF and LOT.
Options (recommendations)
h = place table here
t = place at top of page
b = place at bottom of page

Example of floating figure
 begin{figure}[ht]
 centeringepsfig{file=uni.ps,
width=5cm}
 caption{University of Helsinki}
 label{uni}
 end{figure}
Figure~ref{uni}
shows...

Images
 Use epsfig package
 usepackage{epsfig}
 Including images in main body
 epsfig{file=filename.eps, width=10cm,
height=9cm, angle=90}
 Creating EPS - Use xv and/or xfig.
 MS Power Point, save as GIF and convert to
EPS.

Bibliography by hand
begin{thebibliography}{}
bibitem[Come95]{Come95} Comer,
D. E., {it Internetworking with TCP/IP:
Principles, Protocols and Architecture},
volume 1, 3rd edition. Prentice-Hall,
1995.
end{thebibliography}

Bibliography using Bibtex
 Bibliography information is stored in a
*.bib file, in Bibtex format.
 Include chicago package
– usepackage{chicago}
 Set referencing style
– bibliographystyle{chicago}
 Create reference section by
– bibliography{bibfile with no extension}

Bibliography using Bibtex
@book{Come95,
author=“D. E. Comer”,
title={Internetworking with TCP/IP:
Principles, Protocols and Architecture},
publisher=“Prentice-Hall”,
year=1995,
volume=1,
edition=“Third”}

Bibliography contd.
 Citing references in text
– cite{cuc98} = (Cuce 1998)
– citeN{cru98} = Crud (1998)
– shortcite{tom98} = (Tom, et. al. 1998)
 Creating Bibtex Files
– Use Emacs with extensions.
– or copy Bibtex entries from bibliography
database.

Some Math
begin{center}
{large
$$ y=frac{a^3+2c_{x}}{1+sqrt{b_{x}}} $$

vspace{0.2in}
$$
Q=sum_{i=1}^{j}int_{mu}^{infty}f(x_
{j})dx $$
vspace{0.2in}
$$ Psi = oint_{-
infty}^{infty}f_{xy}({frac{partial
Qx}{partial Qy}})^{Im_{pi}^ prime} $$
}

Tools
UNIX based systems
– xdvi, ghostview, fixps, emacs with
latex/bibtex support.
Windows 98/NT
– Ghostview, Acrobat Distiller, Acrobat
Reader, Scientific Workplace (not the best),
the Bibtex viewer is good. Paint Shop Pro,
Latex and Emacs

Conclusions
 Mathematical Formulae are easy.
 Avoid GUI latex creators. (Lyx, Klyx,
Scientific Word).
 Use the bibtex search engine:

 Consider converting Postscript files to
PDF to conserve space.
