====== Latex ======

===== LaTex Tutorials =====

You can google for Latex tutorials (there are many). 
  *There is a quick and simple introduction [[http://www.maths.tcd.ie/~dwilkins/LaTeXPrimer/TypicalInput.html|here]]
  *For mathematics we use the B-style (for some of the symbols) and the AMS package [[ftp://ftp.ams.org/pub/tex/doc/amsmath/short-math-guide.pdf|AMS]].

I use [[http://miktex.org|MikTex]] on windows and [[http://www.tug.org/texlive/|Texlive]] on my mac (the MacTex distribution). Both distributions come with a free front-end GUI called TexWorks.

''Birthday-Book.zip'' (in the ''Misc'' folder in the SVN) is the template for doing requirements documents. The main tex file ''birthday-book.tex''. This file in turn uses ''defns.tex'' (which in turn uses a number of styles in the folder ''sty''). See below for how to compile these files into PDF.

===== Prism/Command line =====

Texlive is installed on the Prism/Linux machines and Miktex on the Prism/Windows machines.

Here is a small text.tex file

<code>
\documentclass[12pt]{article}
\begin{document}

The foundations of the rigorous study of \emph{analysis}
were laid in the nineteenth century, notably by the
mathematicians Cauchy and Weierstrass. Central to the
study of this subject are the formal definitions of
\emph{limits} and \emph{continuity}.

Let $D$ be a subset of $\bf R$ and let
$f \colon D \to \mathbf{R}$ be a real-valued function on
$D$. The function $f$ is said to be \emph{continuous} on
$D$ if, for all $\epsilon > 0$ and for all $x \in D$,
there exists some $\delta > 0$ (which may depend on $x$)
such that if $y \in D$ satisfies
\[ |y - x| < \delta \]
then
\[ |f(y) - f(x)| < \epsilon. \]

One may readily verify that if $f$ and $g$ are continuous
functions on $D$ then the functions $f+g$, $f-g$ and
$f.g$ are continuous. If in addition $g$ is everywhere
non-zero then $f/g$ is continuous.

\end{document}
</code>

On Prism you can invoke

<code>
pdflatex input.tex
</code>

This produces an input.pdf file that should display as can be seen
[[http://www.maths.tcd.ie/~dwilkins/LaTeXPrimer/TypicalInput.html|here]].

**Note**: Invoke 

<code>
source /cs/local/packages/texlive/cshrc.texlive 
</code>

before you run pdflatex. Even better, put the above line at the end of your ''.cshrc'' file.

===== Prism/TexWorks =====
 
  * At the Prism command line run ''texworks'' (If the workstation is in Windows mode, there should be a shortcut for TexWorks on the desktop).
  * ''File->select-from-template->Latex->article'' and save the file . 
  * Press the green run button. You should see the pdf displayed.
  * Read the manual that comes with the Help menu.

    * The TikZ-UML Latex package can also be used within LaTeX itself to do UML drawings (uses cases, class diagrams, statecharts and sequence diagrams).
