Doxygen allows you to put formulas in the output (this works only for the HTML, 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 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.
Using in-text formulas that appear in the running text. These formulas should be put between a pair of \f$ commands, so
The distance between \f$(x_1,y_1)\f$ and \f$(x_2,y_2)\f$ is \f$\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\f$.
results in:
The distance between and is .
Using in-text formulas that appear in the running text, contrary to \f$ it will not explicitly open the math mode in . These formulas should be put between \f( and \f) commands, so
The LaTeX and Tex logos are: \f(\LaTeX \f) and \f(\TeX \f).
results in:
The LaTeX and Tex logos are: and .
\f[ |I_2|=\left| \int_{0}^T \psi(t) \left\{ u(a,t)- \int_{\gamma(t)}^a \frac{d\theta}{k(\theta,t)} \int_{a}^\theta c(\xi)u_t(\xi,t)\,d\xi \right\} dt \right| \f]results in:
environment
is the name of the environment, the corresponding end command is \f}. Here is an example for an equation array \f{eqnarray*}{ g &=& \frac{Gm_2}{r^2} \\ &=& \frac{(6.673 \times 10^{-11}\,\mbox{m}^3\,\mbox{kg}^{-1}\, \mbox{s}^{-2})(5.9736 \times 10^{24}\,\mbox{kg})}{(6371.01\,\mbox{km})^2} \\ &=& 9.82066032\,\mbox{m/s}^2 \f}which results in:
For the first and third commands one should make sure formulas contain valid commands in 's math-mode. The second command should valid text-mode commands that also work in math-mode when using USE_MATHJAX. For the fourth command the section should contain valid command for the specific environment.
formula.repository
that are written to the html, rtf etc. directories to get rid of an incorrect formula as well as the form_*
files.To have the possibility to define your own commands, for e.g. formula building blocks or consistent writing of certain words, the configuration option FORMULA_MACROFILE can be used. to supply a file with commands. This file can contain \newcommand
and \renewcommand
commands and they are included formulas (image version and MathJax version) as well as in the generated output (for PDF generation).
The \newcommand
(and \renewcommand
) are restricted to a version without optional parameters so only the following types are supported:
e.g.
