Research Tools: LaTex A high quality document preparation system

1. Research Tools: LaTex A high quality document preparation system by Karthikeyan Umapathy

2. Tex (Greek texnologia) – computer program created by Dr. Donald E. Knuth (Stanford University) – 1982 LaTex – a macro package based on Tex with predefined layouts Dr. Leslie Lamport (Microsoft Research) - 1980s

3. LaTex Production Chain Input Text/commands LaTex DVI (device independent) pdfLaTex Postscript pdf printer

4. 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”

5. 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”

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

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

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

9. Writing a document in Latex Title, author Example.tex % This is an example.tex \documentclass [12pt]{article} \begin {document} \title {This is an example} \author {James Bond} \maketitle \end {document} (1) latex Example.tex Example.dvi (2) dvips Example.dvi Example.ps (3) ps2pdf Example.ps Example.pdf

10. Writing a document in Latex Font size \tiny to \Huge Example.tex % This is an example.tex \documentclass [12pt]{article} \begin {document} \noindent This is a test \\ \small {This is a test}\\ \Large {This is a test}\\ \Huge {This is a test}\\ \end {document} (1) latex Example.tex Example.dvi (2) dvips Example.dvi Example.ps (3) ps2pdf Example.ps Example.pdf

11. Writing a document in Latex Section and Subsection Example.tex % This is an example.tex \documentclass [12pt]{article} \begin {document} \title {This is an example} \author {James Bond} \maketitle \section {Introduction} \subsection {Experiment} \end {document} (1) latex Example.tex Example.dvi (2) dvips Example.dvi Example.ps (3) ps2pdf Example.ps Example.pdf

12. Writing a document in Latex Equations Example.tex \documentclass [12pt]{article} \begin {document} \title {This is an example} \author {James Bond} \maketitle \section {Introduction} \begin {equation} g_{ \gamma_{n}}(t) = \frac{1}{ \sqrt{s_{n}}}\;g(\frac{t-p_{n}}{s_{n}})\,\exp\left\{j(2\pi f_{n}t+\phi_{n})\right\}, \label {eq1} \end {equation} \end {document}

13. Writing a document in Latex Equations Example.tex \documentclass [12pt]{article} \begin {document} \title {This is an example} \author {James Bond} \maketitle \section {Introduction} \begin {equation} g_{ \gamma_{n}}(t) = \frac{1}{ \sqrt{s_{n}}}\;g(\frac{t-p_{n}}{s_{n}})\,\exp\left\{j(2\pi f_{n}t+\phi_{n})\right\}, \label {eq1} \end {equation} \end {document} S_n - subscript S^n - superscript Math commands

14. Writing a document in Latex Figures Example.tex % This is an example.tex \documentclass [12pt]{article} \usepackage {epsfig, graphicx} \begin {document} \begin {figure} \epsfxsize =4.5in \centerline {\epsffile{platypus.eps}} \caption {Sample Figure.} \label {fig1} \end {figure} \end {document} (1) latex Example.tex Example.dvi (2) dvips Example.dvi Example.ps (3) ps2pdf Example.ps Example.pdf

15. Writing a document in Latex Example.tex Table % This is an example.tex \documentclass [12pt]{article} \usepackage {epsfig, graphicx} \begin {documen} \begin {table} \centering \begin {tabular}{|c|c|c|c|c|} \hline Method &Groups & Normal & Abnormal & Total \\ \hline LR & Normal & 40 & 11 & 51\\ & Abnormal & 17 & 22 & 39 \\\hline \% & Normal & \bf{78.4} & 21.6 & 100 \\ & Abnormal & 43.6 &\bf {56.4} & 100 \\\hline \end {tabular} \caption {Sample Table} \label {tab1} \end {table} \end {document}

16. Writing a document in Latex References within a document Example.tex % 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} Very easy to manage all the references in long documents

17. Writing a document in Latex Citing other works Example.tex % 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} Order and numbering of the references are automatic. Inserting a new citation reorders the references ( a cool feature !)

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

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

20. 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 www.rnet.ryerson.ca/sar useful links (tools, tutorials)
