Pipmak uses Lua as its scripting language. For an overview of the  
built-in mathematical capabilities of Lua, see <http://www.lua.org/manual/5.0/manual.html#5.5

possible to do them "by hand" by element-wise looping over Lua lists.  
That should work well enough if all you need to do is multiplying a  
4x4 matrix to a vector, but it might not cut it if you're trying to  
diagonalize 1000x1000 matrices or something. If you need something  
more efficient, I could imagine that Lua bindings to some optimized  
numerical computation libraries exist. You might find something on the  
sites linked from <http://www.lua.org/community.html>, and if you do,  
it could probably be used in Pipmak using the extension module support  
that I'm currently working on.

Does that answer your question?
