Display mathematical equations within your posts and comments.

Put your plain text mathmatical expressions between [pmath size=xx]…[/pmath] tags. The optional size attribute controls how large the images will be displayed. Useful xx integer values range from 8 to 24. Size defaults to 12 when attribute omitted. Pascal Brachet’s PHP Math Publisher library is included.

How To

To toggle to the math mode within your blog’s content, you must use the [pmath size=xx]…[/pmath] markdown tag. The plugin automatically replaces your math text commands into HTML image tags that look sort of like this:
<img src=”MathFileName.png” style=”vertical-align:-xxpx; display: inline-block ;” alt=”your math text command”/>.

The math commands must be separated by a space character or surrounded by {}.


  • [pmath size=12]S(f)(t)=a_{0}+sum{n=1}{+infty}{a_{n} cos(n omega t)+b_{n} sin(n omega t)}[/pmath]
  • [pmath size=24]delim{lbrace}{matrix{3}{1}{{3x-5y+z=0} {sqrt{2}x-7y+8z=0} {x-8y+9z=0}}}{ }[/pmath]
  • [pmath]delim{|}{{1/N} sum{n=1}{N}{gamma(u_n)} – 1/{2 pi} int{0}{2 pi}{gamma(t) dt}}{|} <= epsilon/3[/pmath]
