==============
|
|
This file contains JavaScript functions to convert ASCII math notation
|
|
and (some) LaTeX to Presentation MathML. The conversion is done while the
|
|
HTML page loads, and should work with Firefox and other browsers that can
|
|
render MathML.
|
|
|
|
Just add the next line to your HTML page with this file in the same folder:
|
|
|
|
<script type="text/javascript" src="ASCIIMathML.js"></script>
