We have more or less the same in a function "ïsOctave.m" (maybe even with a
persistent variable inside). That function lives in our script library (a
collection of dedicated m-file subdirs) that is in a path set up in a
startup script called by both Matlab and Octave.
No idea if it's faster (I do suspect some function calling overhead) but as
a function it's easy to put in an if clause:
if (isOctave)
  ...
else
  ...
end %if
