```python
tensorplay.fft._transforms.hfftn(input, s=None, dim=None, norm=None, *, out=None)
```

N-dimensional FFT of a Hermitian-symmetric spectrum; real output.

Applies [hfft()](tensorplay.fft._transforms.hfft.html#tensorplay.fft._transforms.hfft) (conjugate + complex-to-real) along the final
transformed dimension, then [ifft()](tensorplay.fft._transforms.ifft.html#tensorplay.fft._transforms.ifft) over the remaining dimensions.
