The user manual has a suggestion that follows the same lines:

    
https://octave.org/doc/interpreter/How-to-Distinguish-Between-Octave-and-Matlab.html

As the manual shows, if you are assigning a variable anyway, avoid the
if-else:

    octave = (exist('OCTAVE_VERSION', 'builtin') == 5);

and as others have suggested, you could make that persistent and/or
global, depending on your needs.
