Follow-up Comment #4:
It seems to me that this bug is exactly bug #43742.
In the normal case, ifft(fft(rand(128,1))) returns a complex vector. If the
user wants to force the conjugate symmetric inverse transform, it should be
done with ifft(fft(rand(128,1)),'symmetric'). That is precisely bug #43742. I
don't think there is any other appropriate way to do this. Am I missing
something? Closing as a duplicate.
