Advanced Formulae in Latex

Remember when you couln’t think of the correct commands to write a certain formula in latex because it’s been a year since you did it the last time? This might help you find the light.

Vectors

Using

1	\newcommand{\ve}[1]{\mbox{\bf #1}}

in your preamble, you can easily write vectors as follows:

1
2
3

\begin{equation}
\mathscr{L}(\ve v_i) = \ve v_i - \frac{1}{\left| N_i \right|} \sum_{j\in N_i} \ve v_j
\end{equation}

Matrices

You always need matrices. Try this code:

1
2
3
4
5
6
7
8
9
10

\begin{equation}
\begin{pmatrix}
A & A_k
\end{pmatrix}
\begin{pmatrix}
D \\
D_k
\end{pmatrix}
= 0
\end{equation}

Multi-case definition

This code comes in handy to define certain funtions or matrices:

1
2
3
4
5
6
7
8

\begin{equation}
A_{ij} = \left\{
\begin{array}{l l}
1 & \quad (i,j) \in K \\
0 & \quad \text{otherwise} \\
\end{array}
\right
\end{equation}

Latex Fonts in Illustrator

I recently wanted do insert a formula into a Adobe Illustrator figure. Since I didn’t find a way to do so directly in Illustrator and copying a formula from MS Word didn’t work properly, I wanted to copy the formula from a latex generated pdf (or ps) file. This, however, didn’t work either, as some latex fonts (CMR8, ect.) were missing. There’s probably a way to include them while generating the pdf file. But the easiest way I found was to copy all type 1 font files from my latex distribution C:\Program Files (x86)\MiKTeX 2.8\fonts\type1\public\amsfonts\cm to the windows font directory C:\Windows\Fonts. That worked. Yay.
