The syntax is not documented in a human-readable form (spare the 
programmers). There is no BNF-like form for you to read.

If you are interested in a parser, you can just look at the parser 
implemented by Octave. It's written using the GNU tools for parser 
generation (i.e. compiler compilation). They are called flex and bison.

Lexical analyzer generation (flex input):

Parser generation (bison input):
