Leo,

There are packages for latex that would parse your code and highlight
it nicely, e.g.
http://stackoverflow.com/questions/1966425/source-code-highlighting-in-latex
This may be more useful than converting octave to latex (which to me
sounds only useful when defining functions, like in a CAS). with those
tools you just insert your code and it looks nice in your latex
document, no conversion needed.

I do not know if a latex output has been already implemented. However
if you would like to give ti a try, the instructions of jwe here
http://wiki.octave.org/User:KaKiLa#make_output_format_a_valid_input_format
may be useful. Basically you could define a new output function that
does the conversion to tex. It may be not trivial though.

Cheers
