Introduction to LATEX for Computer Scientists

Simon Funke, Jonathan Feinberg

September 29, 2015

Overview

LATEX � A document markup language

Write what you mean (WYSIWYM), not what you see(WYSIWYG).

Easy consistency throughout large/many documents

Professional typesetting

Highly customizable and extendable

Compile to multiple formats

Superb math-typing

Presentations/Slides

Bibliography

etc.

Aligning multiple expressions

\begin{align*}

a &= 1, 2, 3 & b, c, d &= 4 \\

\pi &\approx \frac{22}{7} & 1\cdot 2\cdots n &\equiv n!

\end{align*}

a = 1, 2, 3 b, c , d = 4

π ≈ 22

71 · 2 · · · n ≡ n!

Code

The package minted allows to add Python/C(++)/Java withsyntax highlighting

minted requires Pygments, a Python package for codehighlighting. Pygments supports over 300 supported languagesand text formats

Alternative: listings package.

Python code with minted

...

\usepackage{minted}

\begin{document}

\begin{minted}{python}

import sys

def func():

print "Hello world"

\end{minted}

import sys

def func():

print "Hello world"

Customize minted

\begin{minted}

[frame=lines,

framesep=2mm,

linenos]{python}

UiO (and other) custom themes

University machines support the UiO theme

All UiO styles and templates can be downloaded from

http://www.mn.uio.no/ifi/tjenester/it/hjelp/latex/

Move (unpacked) material to texmf (linux, optional)

$ mv file_or_folder /usr/share/texmf/tex/latex/

Add folders to latex path

$ mktexlsr path/to/files_and_folders

(Neglect arg if loading texmf folder.)

Bibliography

A thesis must have a bibliography!

LATEX support bibliography through bibtex.

Bibliographies are stored in a separate .bib �le

Manage the bibliographies through reference managementssoftwares like Zotero:

Bibtex in practice

% example.tex

\documentclass{article}

\begin{document}

Citing \cite{xkcd}.

\bibliographystyle{plain}

\bibliography{ref_file}

\end{document}

% ref_file.bib

@book{xkcd,

title = {What If},

author = {Monroe, R.},

year = {2014},

isbn = {9780544272996},

publisher = {Houghton Mifflin Harcourt}

}
