Mathtex AsciiMath Matrices

[Dev]

Hi,

I am using tinyMCE with AsciiMath and Mathtex, Everything works fine
except Matrices for e.g.

my mimetex cgi is very much able to get the desired result from :
[[a,b,c],[d,e,f],[g,h,i]]

but mathtex fails miserably
I've tried all sorts of formating, but none help, I am fine even if i
am able to do this using latex format.
