3 Today Introduction to Latex - Basic commands - Structure of the document - Mathematical expressions - Adding image Assignment 2 (and 3)

4 LaTeX A document preparation system developed by L. Lamport based on the TeX system created by D. Knuth. Will be written as "Latex" for simplicity. Takes a document created using the Latex markup language and converts into a format suitable for printing (typically PDF). Free software.

5 Latex (cont) Powerful support for mathematical formulas and diagrams, citations, cross-references, footnote, bibliographies, etc. Commonly used by publishers for preparation of books and academic journals. Flexible programming environment for creating new commands, environments, packages, etc.

6 Using Latex on your own computer Main Latex website: On MacOS: Install MacTeX: On Windows: Install MiKTeX: Both distributions contain a complete system (including editor) Plenty of documentation online Easy to find help!

7 Advantage of Latex: Latex vs. Word - Portable: can be used on any computer - Stable: old documents can still be read - Standard in Academic world - Easier to use but only after some time Drawback of Latex: - Not WYSIWYG - Not so common outside of university - More difficult at the beginning

8 Latex General Idea Focus on the content Do not focus on the design Latex will choose automatically the best design How to use Latex: 1 Write a source file report.tex 2 Compile using Latex 2 Fix the errors and compile again 3 Check the result, typically report.pdf

9 Latex First Example \documentclass{article} \title{my first Latex document} \author{francois Bonnet} \begin{document} Always start with \documentclass[ ]{ } Latex commands use backslash: \commandname { } is for mandatory arguments [ ] is for optional arguments Use the \title{ }, \author{ }, and \date{ } to give title, author, and date \maketitle This is my first document written in Latex. It seems difficult but as we will see, it is not so difficult! \end{document} The main content of the document is between the \begin{document} and \end{document} commands The command \maketitle creates the top of the document

10 Latex In this room Use TeXShop to write Latex documents Compile using the Typeset button (or Cmd-T shortcut) Check/correct errors (if any)

11 Latex First Example \documentclass{article} \title{my first Latex document} \author{francois Bonnet} \begin{document} \maketitle This is my first document written in Latex. It seems complex but as we will see, it is not so difficult to write good documents using Latex! \end{document}

12 Latex Document structure... \begin{document} \section{how to use matplotlib} I describe here how to use matplotlib Use the commands \section{ } and \subsection{ }to structure your document. \section{how to use \LaTeX} I describe here how to use LaTeX. I will first explain history of Latex, then some basic commands, then... New paragraph starts after an empty line. Use an empty line to start a new paragraph. \subsection{history} Bla bla bla bla \subsection{basic commands} Bla bla bla bla Automatic numbering of sections and subsections Try subsubsection or \subsection{something else} \end{document} subsubsubsection or

13 Latex List... \begin{document} The itemize environment can be used to create a list of items. There are three main OS: \begin{itemize} \item macos To create numbered list, one should use the enumerate environment. \item Linux \item Windows \end{itemize} Try enumerate on your computer. Try nested lists on your computer. \end{document}

14 Latex Math expressions... \begin{document} It is very easy to write ``complex'' mathematical expressions: \begin{itemize} \item $\alpha$, $\beta$, $\gamma$, $\Gamma$, \ldots \item $\sqrt{256} = 16$ \item $x_1 + x_2 + x_3$ \item $(x+y)(x-y) = x^2 - y^2$ \end{itemize} \[ \sum_{n=1}^{\infty} \frac{1}{n^2} = \frac{\pi^2}{6} \] \end{document} Inline mathematical expression appears between $...$ Display mode is activated using \[ \] and should be used for more complex formulas Use the `` and '' for quotes. Do not use the (double quotation mark) Note also the \ldots command that produces

15 \documentclass{article} Latex Insert images \usepackage{graphicx}... \begin{document} Use the graphicx package. Need to add it in the preamble with \usepackage{graphicx} \begin{figure} \centering \includegraphics[width=6cm]{figure4.pdf} \caption{a simple curve} \end{figure} \begin{figure} Use the figure environment to insert figures in the document. Specify the size of the figure with the width or height. \centering \includegraphics[width=\textwidth]{figure4.png} \caption{the same curve but larger and from a.png file} \end{figure} Use width=\textwidth to specify the full textwidth. \end{document}

16 Assignment 2 Create a Latex document assign2.tex that contains (at least): - A title and your name (as author) - Some short text (just a few lines) - The mathematical expression on the right: (Attention to parenthesis, look for help online) - One picture (for example, the one from Assignment 1) Typeset the file assign2.tex to create assign2.pdf Compress assign2.tex, the picture, and assign2.pdf into assign2.zip Submit via OCW-i the compressed file before July 10.

17 Assignment 3 Write a short document (2-5 pages) in Latex You can choose the topic: About your country, about sport, about videogame, about music, It should contains at least three graphs (made with matplotlib) of at least two different types (line, bar, pie, histogram, ) Deadline probably around end of July Do not wait for the last minute to start it!
