Detecting Octave

[Eyal Doron]

Hi,
   I would like an .m file to detect if its running under Matlab or
Octave. Anybody have a generic solution?

Before you start, things like

if exist(whitespace_in_literal_matrix)

don't work. I could search for .m files which exist in one and not the
other, but that is inelegant and version dependent. Any other way? If not,
maybe a builtin function should be included in the future?
