Follow-up Comment #2:

Thank you for the detailed bug report and example. Fortunately, this bug has
already been fixed in more recent versions of Octave, so all you need to do is
to upgrade your Octave installation.

In Octave 4.2 and newer:


>> f = @(x) atan (x) ./ (1 + exp (-x .^ 2));
>> fd = complex_step (f, 2)
fd = 0.2746237281548576
