```python
tensorplay.fft._transforms.hfft(input, n=None, dim=-1, norm=None, *, out=None)
```

Computes the 1-D FFT of a Hermitian-symmetric spectrum; real output.

Equivalent to [irfft()](/docs/generated/tensorplay.fft._transforms.irfft.html#tensorplay.fft._transforms.irfft) applied to input.conj(); n is the
output length (default 2 * (input.size(dim) - 1)).
