tensorplay.fft.hfft(input, n=None, dim=-1, norm=None)[[source]](../_modules/tensorplay/fft.html#hfft)

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

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