Distinguishing Octave from Matlab

[Michael Goffioul]

What I did once in such case is using a test like:

if (exist ('octave_config_info') ~= 0)
  % this is octave

else
  % this is not octave

end

Of course, this does not work if you have the (bad) idea to define
a variable named octave_config_info in Matlab...
