I haven't used it, but there's an oct2mat on the octave-forge site. 
The link is http://octave.sourceforge.net/oct2mat.tar.gz

It's great that people want to use octave, but it's really a shame if
price is the driving force. Octave should be used, because you can't (or
at least shouldn't) do science when working on a "black-box" system like
matlab. So please tell people to use octave because of the freedom and
because of the price. At least that's my opinion.

I think (haven't used matlab in a long time) you can't end a function in
matlab with a keyword, only end-of-file, or a new function.

I don't know the reason, but it might be related to # being the standard
shell script comment. With octave supporting comments beginning with #,
it is possible to create an octave script that can be launched from the
terminal, by setting the she-bang (I think that's what it's called) to
#!/usr/bin/octave
