To do this in Matlab

  set (gca, 'fontname', 'symbol')

My octave does not support that behavior which may be a problem local to my computer (?).

Can someone verify that Octave has a symbol font?

If it does work, it will change the fontname for the x/y/z labels as well. To correct that ...

  set (get (gca, 'xlabel'), 'fontname', 'Helvetica')
