mathpublish Plugin

This plugin is based on phpmathpublisher by Pascal Brachet to allow inclusion of properly rendered mathematical formulae in DokuWiki pages.

This plugin was originally written by Christopher Smith and named math2.

This is a completely self-contained PHP solution. It requires no third party packages. It makes use of php's GD library and freely available fonts¹⁾ to create an images for each formula. The plugin script, phpmathpublisher and the required fonts are all included in the download package.

Search and install the plugin using the Extension Manager. Refer to Plugins on how to install plugins manually.

To run this plugin your PHP installation needs to have:

• tokenizer library
• gd library
• png capabilities, i.e. libpng, which also requires the zlib library
• freetype font library

Most default installs of PHP (eg. at web hosts) do have all these requirements fulfilled anyway. For full details refer to the PHP documentation.

Example:

<m>S(f)(t)=a_{0}+sum{n=1}{+infty}{a_{n} cos(n omega t)+b_{n} sin(n omega t)}</m> 
<m 8>delim{lbrace}{matrix{3}{1}{{3x-5y+z=0} {sqrt{2}x-7y+8z=0} {x-8y+9z=0}}}{ }</m>
<m 32>delim{|}{{1/N} sum{n=1}{N}{gamma(u_n)} - 1/{2 pi} int{0}{2 pi}{gamma(t) dt}}{|} <= epsilon/3</m>

Result²⁾:

The general syntax to embed a formulae is this:

<m size>...mathematical formulae...</m>

• size (optional) the base glyph size in pixels - default value: 12.
• alignment can be controlled in the same way as DokuWiki images, one space to the left to right align, one to the right to left align, one on each side to centre.
