\renewcommand{\thesection}{\Alph{section}} | |||
% Changes subsections to use lowercase letters | |||
\renewcommand{\thesubsection}{\thesection.\alph{subsection}} | |||
</syntaxhighlight> | |||
===Programming=== | |||
Latex is a turing complete language.<br> | |||
You can use if statements and for loops in latex.<br> | |||
===Custom Commands=== | |||
You can define your own commands using <code>\newcommand</code> | |||
<syntaxhighlight lang="latex"> | |||
\newcommand{\notdone}{{\color{red} Not done!!}} | |||
</syntaxhighlight> | |||
===Custom Operators=== | |||
Latex packages like amsmath come with operators such as <code>\sin</code> and <code>\log</code>.<br> | |||
To get normal text for custom functions like arcsin, use <code>\operatorname{arcsin}</code>.<br> | |||
Below are some potentially useful math operators. | |||
<syntaxhighlight lang="latex"> | |||
\DeclareMathOperator{\Tr}{Tr} | |||
\DeclareMathOperator{\VCdim}{VCdim} | |||
\DeclareMathOperator{\sign}{sign} | |||
\DeclareMathOperator{\rank}{rank} | |||
\DeclareMathOperator*{\argmin}{argmin} | |||
\DeclareMathOperator*{\argmax}{argmax} | |||
</syntaxhighlight> | |||
;Notes | |||
* Adding <code>*</code> puts subscript elements beneath the operator. | |||

To have a newline in a cell, you can use the [https://www.ctan.org/pkg/makecell makecell] package. | |||
<code>\makecell{Some really \\ longer text}</code>. | |||
To make this align left: <code>\makecell[l]{Some really \\ longer text}</code> | |||
For multirow cells, you can use <code>\multirowcell{5}{Numbers\\from\\ 1 to 5}</code>. | |||
By default, this will align center. You can make it align left: <code>\multirowcell{2}[0pt][l]{Number\\ Letter}</code>. | |||

Typeset all of your papers using latex.
Installation
No Install
Use Overleaf to create latex documents in a web browser.
Partial Install
Download MikTex. It includes the TeXworks editor and will download packages as you use them. This will not take up as much disk space as a full install but will require internet access to download new packages.
Full Install
Windows
Download TexLive using the ISO images.
This is ~4 gigabytes since it includes all the popular LaTeX packages and takes a while to install.
You'll also need an editor. I recommend installing Atom with the following packages:
latex
for calling the TexLive compilerlanguage-latex
for syntax highlightingpdf-view
for viewing the compiled pdf.
apm install latex language-latex pdf-view
Linux
sudo apt install texlive-full
Compile tex documents with
pdflatex [mydocument.tex]
- Note to add bibliography, you need to run
pdflatex
,bibtex
,pdflatex
orrubber --pdf
.
Usage
Fancy Math Font
See this answer.
% Use mathbb for the set of reals R or the set of complex numbers C
% Requires amsfonts
\mathbb{R}
Spaces
See Reference
Spaces in mathematical mode.
\begin{align*}
f(x) =& x^2\! +3x\! +2 \\
f(x) =& x^2+3x+2 \\
f(x) =& x^2\, +3x\, +2 \\
f(x) =& x^2\: +3x\: +2 \\
f(x) =& x^2\; +3x\; +2 \\
f(x) =& x^2\ +3x\ +2 \\
f(x) =& x^2\quad +3x\quad +2 \\
f(x) =& x^2\qquad +3x\qquad +2
\end{align*}
Units
For spacing between elements, use \hspace
or \vspace
.
\hspace[4mm]
Units in Latex
You can specify spacing in pt, mm, cm, ex, em, bp, dd, pc, in
Indents
Section
\hspace*{5mm}\begin{minipage}{\dimexpr\textwidth-5mm} Indented Section \end{minipage}
Sections
Numbering
To change the section numbering from numbers to letters, add the following:
% Changes sections to use capital letters
\renewcommand{\thesection}{\Alph{section}}
% Changes subsections to use lowercase letters
\renewcommand{\thesubsection}{\thesection.\alph{subsection}}
Programming
Latex is a turing complete language.
You can use if statements and for loops in latex.
Custom Commands
You can define your own commands using \newcommand
\newcommand{\notdone}{{\color{red} Not done!!}}
Custom Operators
Latex packages like amsmath come with operators such as \sin
and \log
.
To get normal text for custom functions like arcsin, use \operatorname{arcsin}
.
Below are some potentially useful math operators.
\DeclareMathOperator{\Tr}{Tr}
\DeclareMathOperator{\VCdim}{VCdim}
\DeclareMathOperator{\sign}{sign}
\DeclareMathOperator{\rank}{rank}
\DeclareMathOperator*{\argmin}{argmin}
\DeclareMathOperator*{\argmax}{argmax}
- Notes
- Adding
*
puts subscript elements beneath the operator.
Programming
For Each Loops
\foreach [count=\i] \j in {A,B,...,H}{
Element \i~is \j\\
}
Page Layout
There are many packages which adjust the page layout.
You can use the package wordlike
for a MS Word layout.
Font

\documentclass[12pt]{article}
- Font type
- Times New Roman -
\usepackage{mathptmx}
Tables
Multirow and Multicolumns
\usepackage{multirow}
\multirow{3}{4em}{Dataset A}
Newlines
stackexchange line break in table cell
linebreak in multirow
To have a newline in a cell, you can use the makecell package.
\makecell{Some really \\ longer text}
.
To make this align left: \makecell[l]{Some really \\ longer text}
For multirow cells, you can use \multirowcell{5}{Numbers\\from\\ 1 to 5}
.
By default, this will align center. You can make it align left: \multirowcell{2}[0pt][l]{Number\\ Letter}
.
Table Generator
https://www.tablesgenerator.com/ can generate table code from existing tables.
Figures
\begin{figure}[!htbp]
\includegraphics[width=\linewidth]{/path/to/figure}
\caption{}
\label{}
\end{figure}
Be sure to use vector figures (pdf or pgf) instead of raster ones (png, jpeg).
See https://timodenk.com/blog/exporting-matplotlib-plots-to-latex/ on how to export matplotlib to pgf.
In the snippet [!htbp]
represents the placement preferences.
!
means to ignore some placement limitationsh
mean to place the figure heret
means top of the page.b
means bottom of the page.p
means to place it on a figure only page.
If you add the the float package, you can also use [!H]
which is a more strict version of [!h]
.

Document Class
Overleaf Writing your own class
Document classes are .cls
files which provide a layout for your document.
By writing your own document class, you can ensure a consistent layout across multiple latex documents.
You can also encapsulate commands and macros or package requirements within your document class.
