I tend to use

if (exist('OCTAVE_VERSION'))
  % Octave code
else
  % Matlab code
end

Is there something else that can even parse dot-m files than Matlab and
Octave? Why can't we just assume if its not octave, its matlab.

Why do we need Mathworks consent in this case, unless they create an
inbuilt variable OCTAVE_VERSION just to annoy octave users.

The original auther might also want to look at the "automatic_replot"
internal variable
