tensorplay.fft.hfftn(input, s=None, dim=None, norm=None)[[source]](../_modules/tensorplay/fft.html#hfftn)

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

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