Doxygen allows you to put LATEX formulas in the output (this works only for the HTML, LATEX and RTF output. To be able to include formulas (as images) in the HTML and RTF documentation, you will also need to have the following tools installed

• latex: the LATEX compiler, needed to parse the formulas. To test I have used the teTeX 1.0 distribution.
• dvips: a tool to convert DVI files to PostScript files I have used version 5.92b from Radical Eye software for testing.
• gs: the GhostScript interpreter for converting PostScript files to bitmaps. I have used Aladdin GhostScript 8.0 for testing.

For the HTML output there is also an alternative solution using MathJax which does not require the above tools. If you enable USE_MATHJAX in the configuration then the latex formulas will be copied to the HTML “as is” and a client side javascript will parse them and turn them into (interactive) images.

There are four ways to include formulas in the documentation.
