Hi Jeremiah, Absolutely. Here are some quick notes - Org can recognise simple LaTeX constructs inline, without any special markup section 11.7 of the manual http://orgmode.org/org.html#Embedded-LaTeX - The basic way to place more complex fragments of latex in an Org document is in a #+begin_latex block section 12.6 of the manual http://orgmode.org/org.html#LaTeX-and-PDF-export - Personally I use the listings package to format pseudocode, e.g. #+begin_latex \begin{algorithm} \caption{An algorithm} \label{alg:myalg} \begin{lstlisting}[mathescape,escapeinside=''] '\foreach individual $i$' '\foreach group $k$' $\gamma_{ik} \getsp Q_{k}\prod_{l}\prod_{a=1}^{2}P_{lkX_{ila}}$ \end{lstlisting} \end{algorithm} #+end_latex - Don't forget the nice Org functionality like C-c ' to view the latex code in a latex-mode buffer (manual section 11.3), and C-c C-x C-l to view a png image of the latex fragment (manual section 11.7.4). - The latex can also be included in HTML export. By default this uses png images, but check out this thread for using MathJax and jsMath to have javascript-mediated rendering of LaTeX formulas in HTML with genuine fonts http://thread.gmane.org/gmane.emacs.orgmode/28259 - You can use a #+latex_header line to specify additional latex preamble lines. E.g. I defined the \foreach command in a file emvbpl.sty and make sure that file is included with #+latex_header: \usepackage{emvbpl} - In addition, latex can be included inside begin_src latex blocks, to achieve a variety of extra functionality, and also some of the same functionality as above. chapter 14 http://orgmode.org/org.html#Working-With-Source-Code Don't hesitate to come back to this list with further questions.
