I assume your code looks like this (you've shown nothing, so it's a
good assumption):

if (exist ('OCTAVE_VERSION'))
  sleep (35); % it's Octave, be slow
else
  sleep (0.1); % it's Matlab, be fast
end

the solution is simple, just use 0.1 in the first branch as well. You
can even outperform Matlab by using a lower value!
