It supports MathML 2.0, as well as other math formats. It's available for Windows, Linux, and MacOS. It can be called to edit an equation file from the command line:
Code: Select all
"c:\Program Files\LibreOffice\program\smath.exe" --nologo eqn63.mml
but I simply lack the Java knowledge to do this. I am posting the request here so that others can voice their support for it.
OpenOffice has a similar equation editor (OpenOffice Math), but it currently supports only MathML 1.0.
