What is LaTex

• LaTeX pronounced as “tech”• not like latex gloves!

• LaTeX is a document preparation system for producingprofessional-looking documents, it is not a word processor.

Introduction

• TeX is essentially a Markup Language (like HTML, XML and RTF)

• TeX written by Donald Knuth in 70´s– A revolution in typesetting

• Latex is an extension of TeX–Macro packages to make TeX easier to use

Latex vs. Word Processors

• High typeset quality• Easy to include math formulas• Source file format is 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

Getting Started

– Windows• TeXnicCenter• proTeXt

– Linux• TeXLive

– Mac• LyX & MacTeX

Macro package

How LaTeX works?

• TeX is a typesetter– You write and TeX will place it on the page

Parts of a LaTeX Document

• First line of all LaTeX documents• Specifies the type of the document

\documentclass articlereportbookletter

Basic Classes

Parts of a LaTeX Document

Start with \begin. . .End with \end. . .

… \endequation\enddocument

Parts of a LaTeX Document

• Everything between \documentclass and \begindocument

• Use for customizing the formatting

Body of Text

• Start with \begindocument• End with \enddocument• Typesetting Text– \\ or \newline and \newpage– Bold \textbfITER or \bf – Italics \emph………… or \textit……… or \it– Underline \underline…………

Advantages of LaTeX

• Professional typesetting– Best output

• It is the standard for scientific documents• Processing Mathematical (& other) symbols• Meaning based structuring (rather than appearance)• Knowledgeable and helpful user group• Its FREE!• Platform independent

Disadvantages of using LaTeX

• “Hard to write disorganized documents”• Learning Curve• Customizing is tedious.

Conclusions

• Latex is optimal for master and phd thesis• Mathematical formulae are easy. • Consider converting Postscript files to PDF (more

widespread in Windows world) and to conserve space.
