Introduction
• TeX is low-level markup and programming language to typeset the
document attractively and consistently
• Created by Donald Knuth in 1977.
• Pronounce it like first syllable of “technical”.
• It works similar to HTML, XML.
• Learning to write program in Tex is time consuming.
• Fortunately, document preparation systems based on TeX provide some
pre-built macros to reduce the user effort.
• One of the popular macro package is LaTeX.

LaTeX
• LaTeX (pronounce as Lah-tech or Lay-tech) is created by Leslie Lamport.
• It is a TeX-based document preparation system, and actually a set of macros
for TeX.
• LaTeX converts source code combined with markup into high quality
document.
• Aim: takes care of formatting process.
• Many of the packages or styles developed by other authors are bundled with
LaTeX software distribution. More can be found in CTAN(Comprehensive
TeX Archive Network http://www.ctan.org ).

• Advantages:
 Complete concentration on documents not with layout of document.
 No need of manual type settings of height, width etc.
 Mathematical formulae can be easily typeset
 Index, footnotes, citations and references are generated easily.
 Forced to structure your documents correctly
• It natively supports PDF (Potable Document Format), DVI(Device
Independent) file format but also PostScript, PNG, JPEG etc by using other
software.

Installation
• LaTeX is not a program by itself, it is a language.
• To use LaTeX, need to have the following:
 TeX Distributions
 Text editor
 Bibliography management program
 DVI or PDF viewer

TeX Distributions
• The distributions (have compiler, fonts and LaTeX macro set) for different
Operating Systems:
 TeX Live -----for BSD, GNU/Linux, Mac OS X and Windows
 MikTeX------for Windows
 MacTeX-----for Mac OS X
• Compilers or Engines: generate output files from source
 luatex, lualatex----TeX engine with Lua scripting
 Pdftex, pdflatex---PDF compilers
 tex, latex -----------DVI compilers
 xetex, xelatex------TeX engine which uses Unicode

Editors
• TeX and LaTeX documents are all text files and can be opened and
modified with all text editors (Ex: notepad, EditPlus) but not word
processor (Word, OpenOffice).
• Dedicated LaTeX editors are more useful.
 Cross platform: BaKoMa TeX, Emacs, gedit-latex-plugin, LyX,
TeXmaker, TeXstudio, TeX works, vim
 BSD* and GNU/Linux: kile, Gumni, LaTeXila
 Mac OS X: TeX Shop,
 Windows: Led, TeXnicCenter, WinEdt, WinShell

Bibliography Management
• Bibliography files have “.bib” extension and are most easily edited or
modified using a management system.
• GUIs feature a DB form, in which information can be entered for each
reference item and resulting text file can be easily used by BibTeX.
• Available GUIs:
 Cross-platform: JabRef, Mendely
 Mac OS X: BibDesk
• To use the references from other paper’s bibliography into bibliography
DB, “text2bib” application (http://text2bib.economics.utoronto.ca/) is
helpful.

Viewers
• All LaTeX distributions have a DVI viewer for viewing default output of
latex, or dvitopdf is used to convert from DVI to PDF format.
• There are number of PDF viewers: Adobe Reader, epdfview, Evince, Foxit,
Okular, Sumatra and Zathura.

Online Solutions
• Without installing any thing, LaTeX can be used from number of Web
Hosting Services: Google Documents, Latex Lab, LIMSUP, ScribTeX.com,
ShareLaTeX.com, SpanDeX, verbosus , writeLaTeX.com,publications.li
and Monkey TeX

Installation Procedure for MikTeX
• There are multiple MikTex distributions based on different necessities in url:
http://miktex.org/2.9/setup. Mainly two packages:
 One is “Net installation” provides complete list of packages but a large
size package (1.2GB).
 Another is “Basic installation” provides with basic set of packages and
remaining are installed using package manager after basic installation. It is
of low memory (163MB).
• Procedure for Basic installation requires following steps:
Step1: Download basic MikTeX 2.9 package from url:
http://miktex.org/2.9/setup or http://miktex.org/download

Step2: Then you will be presented with MikTeX copying Conditions.
Read and accept the conditions

Step3: you will be asked to choose the shared version or private version.
Choose one of the two and proceed to next.

Step4: MikTeX will be installed in a standard installation directory.
Click the browse button and specify your preferred location.

Step5: Set the MikTeX settings
1. Set the preferred page size
2. The way installing the missing packages by package manager.
I. Always
II. Never
III. Ask me first

Step6: Review your settings
If your settings are correct according to you, click the start button otherwise
go back for changing your settings.

Step7: Installation progress will be shown to you and this will take few minutes.

Step8: Installation is now finished. Click to close to dismiss the setup wizard.
Then you can begin to use it.

Latex File Structure
 Document class documentclass{article}
Predefined formats: article, report, book ……
 Packages used usepackage{graphicx}
 To add functionality: graphics, reference style……
 Main Body begin{doument} document body here….end{document}
Text , bibliography references,……

Basics of Typesetting
 Document Class: documentclass[options]{class}
Ex: documentclass[11pt,twoside,a4paper]{article}
 class: specifies type of the document and exists in ‘.cls’ format. Some
predefined classes are:
Article: for scientific journals, presentations, invitations…….
IEEEtran: for IEEE transactions format articles
Report : for longer reports having several chapters
…………………
 Options: customizes the behavior of document class. Some Common options:
10pt or 11pt: main font of the document
A4paper or letter paper: size of the paper
Onecolumn or twocolumn: typeset document in one or two columns
………………….

 Use packages: usepackage[options]{package (s)}
Ex: usepackage[margin=2cm]{geometry}
 Package: enhance the capabilities of Latex and exists in ‘.sty’ format. Some
popular and necessary packages are:
graphicx: to include images into document
Amsmath: to improve the mathematical equations environments
rotating: to rotate the text with options of 90o, 270o etc.
geometry: for setting the page layout (width, height, margins etc.)
url: for formatting email addresses, directory paths etc.
………….
 Options: keywords to trigger special features of packages
for url package: obeyspaces--- to allow spaces in url, hyphens---to allow
breaks of url at hyphens.
......................

 Main Body: The document content between begin{document}..end{document}.
 Basic commands for typesetting:
 newline or to start new line
 newpage to start new page
 bf or textbf{..} to get bold font
 emph or textit{..} or it to get italics
 ul or underline{...} to underline the text
 output reserved characters (#, $, %, ^, &, _, {, }, ~, ) using backslash ‘’
 Comments using % character---ignores rest of current line,
line break, all whitespace at the beginning of next line.
 For multi-line comments use “comment” environment (begin{comment}
…..end{comment}) from “Verbatim” package.
 Any environment in Latex is of format: begin{evironment}[args]{args}…
end{environemnt} where arguments in [] are optional but in {} are mandatory.

Insert title and author
• To insert more number of authors separate names with and .
• For easier assistance in case of multiple authors and multiple affiliations use the
package “authblk”, allows both author blocks and foot note type affiliations.
Fig: Example for title and author creation

• Abstract: using begin{abstract}………end{abstract}
• Sectioning the document: LaTeX provides 7 levels of depth
for defining sections.

documentclass{report}
begin{document}
setcounter{secnumdepth}{5}
chapter{chapter}
section{section}
subsection{subsection}
subsubsection{subsubsection}
paragraph{paragraph}
subparagraph{subparagraph}
end{document}
Fig: Example for Sectioning Representation in LaTeX

Text Formatting• Spacing:
 Linespacing linespread{factor}
Ex: linespread{1.3}for one and half spacing
“setspace” package gives more fine grained control with commands
onehalfspacing, doublespacing, singlespacing etc.
 Non-breakable space use tilde ‘~’
 hfill horizontal stretched space pushes rest of content in a line toward
right margin.
 vfill vertical stretched space
 Manual spacing hspace{length}, hspace*{length} for horizontal space
vspace{length}, vspace*{length} for vertical space
 Supports macros for fixed length spacing between two paragraphs
smallskip, medskip, bigskip

• Quotation marks:
for left single quote use the symbol found on the tilde key in keyboard i.e. (`)
for right single quote use apostrophe (‘).
for left double quote use the symbol on tilde key 2 times i.e. (``)
 for right double quote use quotation symbol (“)
• Superscript and subscript: use “fixltx2e” package.
textsuperscript{} Ex: 6textsuperscript{th} ------- 6th
textsubscript{} Ex: Htextsubscript{2}o ------- H2O
using inline math environment ($....$) Ex: 6$^{th}$----------6th
H$_2$O----------H2O
• Line breaks using “”

Paragraph Formatting
• Start new paragraph using an empty line, par
• paragraph{} for new paragraph with heading
• Paragraph Alignment:
• Paragraph indent:
setlength{parindent}{1cm}---indentation of 1cm before starting a paragraph
indent to indent a paragraph which is not indented
noindent to create non-indented paragraph
• Spacing: To have different line spacing for particular paragraph from a whole
document, use “spacing” environment.
Ex: begin{spacing}{2.5}………….end{spacing}

Colors
• Use “color” package.
usepackage{color}
have some declared colors: white, red, yellow………
• Colored text:
textcolor{declared -color}{text} (or)
{color{declared-color}some text}
• page background color: pagecolor{declared-color}
• Colored background: colorbox{declared-color}{text}
• Declare a new color: definecolor{name}{model}{color-spec}
Ex: definecolor{orange}{rgb}{1,0.5,0}

Fonts
• Font Families:
By default three different font families exist.
rmdefault roman or sans
sfdefault sans serif
ttdefault Monospace
To set default font use familydefault variable.
Ex: renewcommand*{familydefault}{sfdefault}
• Font Shapes:
textnormal{} default document font family
textrm{} roman font family
textsf{} sans serif font family
texttt{} tele-type font family
uppercase{} uppercase letters
lowercase{} lowercase letters
textmd{} medium weight font
textsc{} small capitals
sout{} strike through

• Font sizes:
tiny{}
scriptsize{}
footnotesize{}
small{}
normalsize{}
large{}
Large{}
LARGE{}
huge{}
Huge{}
• The physical sizes of these change by depending on the normal size of document.
Ex: if normal size is 10pt  small is 9pt; normal size is 11pt  small is 10pt
• To set arbitrary font size use fontsize{<size>}{<linespace>}
Ex: {fontsize{5cm}{1em}selectfont this is big}

• For Font selection of a part of text
fontencoding OT1 (TeX default) or T1 (extended characters support, better
PDF support, widely used).
fontfamily
fontseries l=light, m=medium, b=bold, bx=very bold.
fontshape it=italic, n=normal, sl=slanted, sc=small capitals
Ex:
{fontencoding{T1}fontfamily{anttlc}fontseries{m}fontshape{n}selectfont
Some text in anttlc…} (or)
usefont{<encoding>}{<family>}{<series>}{<shape>}

Lists
• Three types of lists: itemize, enumerate, description
• “itemize” provide bulleted lists.
begin{itemize}
item first item
item second item
item third item
end{itemize}
• “enumerate” is for ordered lists with numerals (1,2,3…..); Use “enumerate”
package for different types of orders(alphabets, roman numbers etc.)
begin{enumerate}[i]
item first item
item second item
item third item
end{enumerate}

• “description” is useful for glossary; allows to pass item label by passing
optional argument
begin{description}
item[first] first item
item[second] second item
item [third] third item
end{description}
• Nested lists:
begin{enumerate}
item first item
begin{enumerate}
item first sub item
item second sub item
end{enumerate}
item second item
end{enumerate}

Mathematics Environment
• Use “amsmath” package.
• For inline mathematics use $....$.
Ex: the sum is $sum _{x=1}^{10}x^n$-----------
• For equations in separate line use begin{equation}……..end{equation} (or)
begin{eqnarray}……..end{eqnarray}.
• It has support for several symbols, operators, greek letters. For example,
symbols: forall x in X, quad exists y leq epsilon
greek letters: alpha,beta,gamma,Gamma
operators:
cos (2theta) = cos^2 theta - sin^2 theta
lim_{x to infty} exp(-x) = 0

• Fractions: frac{numerator}{denominator}
Ex: frac{n!}{k!(n-k)!}
• Roots: sqrt[magnitude] {}
Ex: sqrt{x}
sqrt[n]{1+x+x^2+x^3+ldots}
• Add text to equations: using text{…}
Ex: 50 text{apples} times 100 text{apples}= text{lots of apples}^2
• list of Latex symbols can be inserted directly from Texmaker directly or can be find
out in http://www.artofproblemsolving.com/Wiki/index.php/LaTeX:Symbols
(or) by using “detexify” (http://detexify.kirelabs.org)
• More about math environment from “amsmath” documentation
[ftp://ftp.ams.org/pub/tex/doc/amsmath/amsldoc.pdf ]

Importing Graphics
• Two ways to include graphics in Latex document
– Creating graphics
– Importing graphics: most usual way to include pictures
• For dvi output format , Latex supports “.eps” figures; for pdf output, it
supports “.pdf”, “.png”, “.jpg” figures.
• Use “graphicx” package.
• Use the command: includegraphics[attr1=val1, ..., attrn=valn]{imagename}
attributes are: width, height
keepaspectratio either true or false
scale to reduce the size
angle to rotate the image
trim has 4 values l,b,r,t to crop from 4 sides
clip should be true for working of the trim

• To include an image use “figure” environment , it allows to specify position of the
image, caption and label to the picture.
position:- h:current position, t: top , b:bottom, p: special page, !:determine good float
position, H: exactly at current position
Caption: to give the automatic numbering and description for the image
label: to give unique name in a document
Ex:
begin{figure}[p]
centering
includegraphics[width=0.8textwidth]{image.png}
label{fig:sampleimage}
caption{an awesome image of a chick}
end{figure}

Tables
• “tabular” environment constructs tables with optional horizontal , vertical lines.
• This environment has the 1st line: begin{tabular}{table-spec}
table-spec: has list of columns with their specifications
l: left-justified column
r: right-justified column
c: centered column
p{width}, m{width}, b{width}: paragraph columns with text vertically
aligned top, middle, bottom respectively.
|: vertical line
||: double vertical line

• some commands needed while constructing table
[width] starts new row, with optional argument of additional vertical
space after a row
hline horizontal line
cline{i-j} partial horizontal line starts with column i, and ends with column j
& column separator
• Ex: begin{tabular}{ |l|c||r| }
hline
1 & 2 & 3 hline
4 & 5 & 6 cline{2-3}
7 & 8 & 9 hline
end{tabular}
• Define multiple columns : use *{number of columns}{column-spec} in table-spec
Ex: begin{tabular}{l*{6}{c}r} creates table with one left justified
column, 6 centered columns, one right justified column.

• Rows spanning multiple columns:
multicolumn{no of columns}{alignment}{contents}
Ex: begin{tabular}{ ll }
hline
multicolumn{2}{c}{Team sheet} hline
GK & Paul Robinson
LB & Lucus Radebe hline
end{tabular}
• Columns spanning multiple rows: use “multirow” package
multirow{num_rows}{width}{contents}
Ex: begin{tabular}{|l|l|l|}
hline
multicolumn{3}{|c|}{Team sheet}
hline
Goalkeeper & GK & Paul hline
multirow{2}{*}{Defenders}& LB & Lucus cline{2-3}
& DC & Michael Duberry hline
end{tabular}

• “table” environment is for position of the table, label, caption support.
Syntax:
begin{table}[position specifier]
centering
begin{tabular}{l}
……….
end{tabular}
caption{This table shows some data}
label{tab:myfirsttable}
end{table}
• Position specifier value can be h, t, b, p, !; default value is tbp
• Excel spread sheets can be imported using “excel2latex” package, and
openoffice spread sheets using “clac2latex” package;
• Latex also has support for importing from other softwares using different
packages.

Labels and Cross-referencing
• Latex supports referencing anything that is numbered in a document, using the
commands:
label{marker} is unique name to refer an object
ref{marker} refers the object and prints the number of it
pageref{marker} prints the number of page on which the object lies
Ex: section{Greetings}
label{sec:greetings}
Hello!
section{Referencing}
I greeted in section~ref{sec:greetings}.
• Figures, tables, equations, items in a list, mathematical equations can be referenced
in the similar fashion.
• “autoref{marker}” command from “hyperref” package provides hyperlink in
addition to the object number.
• A footnote can be created using footnote{<text to be in foot note>}

Bibliography management
• Two ways to include bibliography in a document
1. Using list of bibitem{cite_key} in “bibliography” environment at the end
of a document.
cite{cite_key} to refer an item of bibliography
Ex: The paper~cite{ama2008} explains in detail.
begin{bibliography}{9}
bibitem{ama2008} Aman S, Szpakowicz S (2008) {Using Roget's
thesaurus for fine-grained emotion recognition}. In: Proceedings of the
Third International Joint Conference on Natural Language Processing
IJCNLP 2008, pp 296—302
end{thebibliography}
“9” specifies the number of references allowed; “ama2008” is the unique
cite_key for reference.
Output:

2. creating an external BibTeX database i.e. “.bib” file and include it in
document using two commands at the end of document.
bibliographystyle{style}
bibliography{filename(s)}
style: specifies the bibliography style file name, default is the “plain.bst”
filename(s): list of files(.bib files) containing the references.
Ex: bibliography{plain}
bibliography{samplebibdb}
• “.bib” file: is a flat database file with each reference item as one entry with
different attributes according to the type of it.

Example of an item in bibliography DB:
@inproceedings{ama2008,
author = {Aman, S. and Szpakowicz, S.},
booktitle = {Proceedings of the Third International Joint Conference on
Natural Language Processing IJCNLP 2008},
keywords = {lexicon, om},
pages = {296--302},
posted-at = {2010-09-25 15:43:47},
title = {{Using Roget's thesaurus for fine-grained emotion recognition}},
year = {2008} }
here “inproceedings” is the type of reference paper; “ama2008” is unique
cite_key;
• Latex supports different types of references: inproceedings(conference paper),
article, techreport, masterthesis, inbook (section of book without own title),
incollection (section of a book having own title) etc…

• Multiple citations: use the command
cite{citekey1,citekey2,citekey3…}
• No cite: to appear a reference in the bibliography without referencing in the
main text nocite{cite_key} command can be used.
• Author-year format of referencing: use “natbib” package for different styles
of author-year, numeric citation formats.
usepackage[options]{natbib}
It provides different style files: plainnat.bst, arrrvnat.bst, rmpaps.bst etc…
 provides different citation commands: citet{}, citep{}, citet*{} etc…
options: authoryear for author-year style
square [] around citation numbers
super superscripted numeric citations etc…..
Ex:

General format of Master thesis
• Introductory pages
– Cover page
– Title page
– Certificate
– Declaration
– Acknowledgement
– Abstract
– Table of contents
– List of tables
– List of figures
• Body
– Text (in terms of number of chapters)
– References
• Appendices

• Table of contents: tableofcontents
• List of tables: listoftables
• List of Figures:listoffigures
• List of tables, list of figures are automatically generated with their numbers; To
precede each table/figure with table/figure keyword, use “tocloft” package and
the commands:
renewcommand{cftfigfont}{Figure }
renewcommand{cfttabfont}{Table }
• To include any part of thesis into the table of contents: For example,
addcontnetsline{toc}{chapter}{List of Figures}
Ex o/p:

• In a thesis all introductory pages should have different numbering from the
content of the document. For this purpose, use pagenumbering{roman} before
including all introductory pages, and use clearpage, pagenumbering{arabic}
commands after inclusion of introductory pages and before the inclusion content
of document.
• Each introductory page and each chapter of document can be written separate
tex file and can be included in a main tex file using the command
include{filename}.
• The references should not have page numbers, for this pagenumbering{gobble}
command can be used before including references file.
• To include the appendix, use appendix command before including the
appendices file.

Figure: An example of thesis structure and document body of main
tex file of a thesis

Creating IEEE format document
• For this “IEEEtran.cls” is used.
Ex: documentclass[9pt, conference]{IEEEtran}
• IEEEtran and its support files can be downloaded from IEEEwebsite:
http://www.ieee.org/
• IEEEtran supports different modes: conference, journal, technote, peerreview...
• It supports two text column formats: one column, two column
two paper sizes: a4paper, letter paper
two layouts: oneside, twoside
• It provides slightly different commands than from a usual article and report.

• Title and Author block:
title{Paper Title}
author
{IEEEauthorblockN{author name1}
IEEEauthorblockA{
MVSR Engg College, Hyderabad
email2}
and
IEEEauthorblockN{author name2}
IEEEauthorblockA{
MVSR Engg College, Hyderabad
email1 }}
maketitle
• Abstract and keywords
IEEEtitleabstractindextext{
begin{abstract}
your abstract here......
end{abstract}
begin{IEEEkeywords}
keyword1, keyword2,keyword3
end{IEEEkeywords}}
IEEEdisplaynontitleabstractindextext
IEEEpeerreviewmaketitle

• It supports section, subsection, subsubsection, paragraph for sectioning
the document.
• For bibliography use “spbasic.bst” file for computer science documents. For
example:
