2. TEX?
TEX is a typesetting system that incorporates a
macro processor.
A TEX source document specifies a number of
macro definitions that instruct the TEX engine
how to typeset the document. 
Its implementations are governed by the
principle that the same input should produce the
same output.

3. LATEX?..
LATEX2ε?..
MiKTEX?..
LATEX is a macro package which enables authors to
typeset and print their work at the highest
typographical quality, using a predefined, professional
layout. It uses the TEX formatter as its typesetting
engine.
LATEX2ε includes all the patches which had cropped
up since the release of LATEX 2.09.
MiKTEX is an up-to-date implementation of TEX and
related programs (installation package).

4. The Concept

5. How does LATEX works?
INPUT
.tex : The manuscript
text with interspersed
T
EX commands.
.eps, .pdf, .jpg, etc :
graphics files.
.bib: bibliography.
PROCESS/COMPILE
Latex.exe
Pdflatex.exe
LuaTeX.exe
XeTeX .exe
OUTPUT
1- .dvi or .pdf,
HTML, XML, etc.
2- .log: transcript
3- .aux: auxiliary

6. LATEX vs WYSIWYG
Criterion WYSIWYG LAT
E
X
Document Editing Users need to use the same tool. Users can arbitrary use any text editor.
Changing format
The entire document needs to be
checked for any unwanted results.
The class and some commands need
to be changed.
Layout quality
High quality layout can be reached by
professional users only.
The standard Layout is already high
quality.
Huge contents
program crashes and instability likely
happen with large documents especially
if high-quality graphics incorporated.
Faster since only text and formatting
commands merged and the separate
typesetting steps are only done.
Citation
Requires additional tool such as
Mendeley or Endnote.
It is professionally handled using the
free and built-in BibTeX tool.
compatibility Low compatibility with all editors & OSs.
High compatibility with all editors &
OSs.
Backward compatibilityIs not fully supported. Is not fully supported.
Split work into many files
Usually no practicable solution
available.
Available.
Cost Some are free with limited features.Free

LATEX: Basic Document Structure
The preamble
The content

17. LATEX: Basic Document Structure
Examples:
\documentclass[10pt,a4paper]{article}
\title{You must put the title Here}
\author{The name of first author
\and The name of second author}
\date{15/11/2015}
\begin{document}
\maketitle
You can write anything here. You can write
anything here. You can write anything here.
You can write anything here. You can write
anything here. You can write anything here.
You can write anything here.
\end{document}

18. LATEX: Document classes
Document Classes Description
article
For articles in scientific journals, presentations, short reports, program
documentation, invitations, ...
IEEEtran For articles with the IEEE Transactions format.
proc A class for proceedings based on the article class.
report For longer reports containing several chapters, small books, thesis, ...
book For real books.
slides For slides. The class uses big sans serif letters.
memoir
For changing sensibly the output of the document. It is based on
the book class, but you can create any kind of document with it.
letter For writing letters.
beamer For writing presentations see LaTeX/Presentations).
elsarticle For articles with the Elsevier format.

19. Document Class
Options
Description
10pt, 11pt, 12pt Sets the size of the main font in the document. If no option is specified, 10pt is assumed.
a4paper, b5paper,
letterpaper,...
Defines the paper size. The default size is letterpaper; However, many European distributions of TeX now
come pre-set for A4, not Letter, and this is also true of all distributions of pdfLaTeX. Besides that, a5paper,
b5paper, executivepaper, and legalpaper can be specified.
fleqn Typesets displayed formulas left-aligned instead of centered.
leqno Places the numbering of formulas on the left hand side instead of the right.
titlepage, notitlepage
Specifies whether a new page should be started after the document title or not. The article class does not
start a new page by default, while report and book do.
onecolumn,twocolumn Instructs LaTeX to typeset the document in two columns instead of one.
twoside, oneside
Specifies whether double or single sided output should be generated. The classes article and report are
single sided and the book class is double sided by default. Note that this option concerns the style of the
document only. The option twoside does not tell the printer you use that it should actually make a two-sided
printout.
landscape Changes the layout of the document to print in landscape mode.
openright, openany
Makes chapters begin either only on right hand pages or on the next page available. This does not work with
the article class, as it does not know about chapters. The report class by default starts chapters on the next
page available and the book class starts them on right hand pages.
draft, final
makes LaTeX indicate hyphenation and justification problems with a small square in the right-hand margin
of the problem line so they can be located quickly by a human. It also suppresses the inclusion of images
and shows only a frame where they would normally occur.

31. Including graphics
You can include any type of graphs (jpg, png, bmp, pdf, eps, ps, etc.)
But the most preferable graph types is Encapsulated PostScript (EPS)
Usable by any vector graphic application
Supports transparency
Editable file since it contains a description of the graphic objects using
the PostScript page description language.
Can be enlarged indefinitely without losing quality.
Steps to include graphics to LaTeX document:
1.prepare the .eps graphic
2.Load the graphics or graphicx package
3.Include the graphic in the .tex file

32. Including graphics
Load the graphicx package
Put the following command in the preamble
\usepackage{graphicx}
Include the graph
The options of \Includegraphics
\begin{figure}[h]
\centering
\includegraphics[width=0.7\linewidth]{plot}
\caption{Figure Caption Here}
\label{fig:plot}
\end{figure}
option Description
width change the graphic width
height change the graphic hight
angle rotate graphic counterclockwise with a specific degree
scale scale graphic (% from the original size)
option Description

33. Is there any wizard?
Yes there are several wizards in TeXstudio.
Wizards can help you quickly to do:
Quick starting.
Quick beamer presentation.
Quick letter.
Quick tabular.
Quick tabbing.
Quick array.
Insert graphics (but drag and drop is much easier).
Math assistant.

1.Prepare the bibliography file (.bib), perhaps using jabRef
2.Add the following command in the end of the (.tex) document file,
where the references section is:
Example:
4.Cite the reference in you text using the following command
\bibliographystyle{bibliography style}
\bibliography{bibliograpy database file}
\bibliographystyle{IEEEtran}
\bibliography{your-bib-database}

Multiple citation
Several approaches such as \cite{Lee2009, Jansang2011,
Cecchetti2012, cecchettielAL2012, ruscelli2012} have been
presented in the literature attempting to remedy the deficiency of
the HCCA reference scheduler in supporting QoS for VBR traffics.

50. Getting things together
applying latex template
1.Get the IEEEtrans template from https://www.ctan.org/ or
https://www.ieee.org/conferences_events/conferences/publishin
g/templates.html

2.Extract the template file (which includes IEEEtran.cls)into a folder
3.Copy images files
4.Copy reference.bib
5.add your material in the given template’s places
6.Compile
7.Done!
