WYSIWYG vs. LaTex Focus on content then the appearance Best for writing lot of Math References - Bibliography Manage large documents Professional output quality Predefined layouts Portable – any OS – hardware etc Creative FREE WYSIWIG – “What you see is what you get “ or “What is see is ALL what you get”

WYSIWYG vs. LaTex Learning curve Short documents Custom layouts WYSIWIG – “What you see is what you get “ or “What is see is ALL what you get”

LaTex Classes ArticleReportBookLetter Ordinary documents -paper Large organized Documents -Thesis BooksLetter Many new class files can be created modifying the above 4 base class files (Ex: IEEEtran.cls – derived from article.cls)

% Comments \documentclass [options] {style} \begin {document}. \end {document} Example.tex Writing a document in Latex Predefined classes like article, report, letter or book Comments or notes The document begins here The document ends here Options within a class such as Paper size, font size etc Body of the document

% This is an example.tex \documentclass {article} \begin {document} This is a test \end {document} Example.tex Writing a document in Latex (1) latex Example.tex Example.dvi (2) dvips Example.dvi Example.ps (3) ps2pdf Example.ps Example.pdf

% This is an example.tex \documentclass [12pt]{article} \begin {document} \section {Introduction} \label {intro} This is section on Introduction. \subsection {experiment} \label {exp} This is an example subsection. Please refer Section.\ref {intro} for introduction. Refer Section \ref {exp} \end {document} Example.tex Writing a document in Latex Very easy to manage all the references in long documents References within a document

% This is an example.tex \documentclass [12pt]{article} \bibliographystyle {IEEEtran} \begin {document} \section {Introduction} \label {intro} This is section on Introduction. \subsection {experiment} \label {exp} This is an example subsection. This work is based on the MP algorithm \cite {mallat2} \bibliography {bibfile} \end {document} Example.tex Writing a document in Latex Order and numbering of the references are automatic. Inserting a new citation reorders the references ( a cool feature !) Citing other works

Writing a document in Latex Let us put everything together - \title -\author -\section -\subsection - \section - \subsection - figure -Table - \ref - \cite - \documentclass -\begin - \end - \maketitle

Class, Style files in Latex \usepackage{conf.sty} & \documentclass{journ.cls} Double column and IEEE trans. standard

Getting the TOOLS ! On Unix Platforms - Latex Preinstalled (dept. ) - Xfig – a very good drawing program to create figures On Windows platform -MikTex – Tex for windows (Latex) - Xfig not native in windows (cygwin) - Openoffice (draw) can create *.eps figures - Dia useful links (tools, tutorials)
