Follow-up Comment #8, bug #43673 (project octave):
I wrote a patch that fix the bug for double array when have fftw.
There are other FFT functions need to be fixed. (for different array types,
with or without fftw, inverse or forward transform)
Tests that related to this bug
a=reshape(1:2*2*2, 2,2,2);
assert (fft (a, 1, 3), a(:,:,1))
assert (fft (a, 0, 3), a(:,:,1:0))
assert (fft (a(:,:,1), 1, 3), a(:,:,1))
assert (fft (a(:,:,1), 0, 3), a(:,:,1:0))
assert (fft (ones(2,2,1,2), 1, 4), ones (2,2))
assert (fft (1, 3, 3), ones (1,1,3))
(file #32681)
