If I want a title to read "y = x2" I can type in "title('y = x^2')" and it will output it as described before, or if I want a Greek character, say w, I can type "\omega" like in LaTeX.  Is there some way to do this in Octave?  If so, how?  Thanks.

I had a similar question last spring.  The best answer of the many provided involves the use of the script fig2ps and a slight modification to the octave-forge print.m function so that it generates fig files with "special" text.  You also need to pay attention to the fact that the backslash character "\" is escaped a couple of times in the octave scripts, so you need to write
\\\\omega
instead of
\omega
in the octave plot command legend, or, if you use the octave-forge legend command,
I think you need eight backslashes instead of four.  Weird and annoying, but you get what you want in the output.

Details and an example are on my AU weblog,
