See the guide: Spectral Functions > Discrete Fourier Transforms
Inverse real-valued fast Fourier transform.
Computes the inverse 1-dimensional discrete Fourier transform of a real-valued signal over the inner-most dimension of
The inner-most dimension of
input is assumed to be the result of
fft_length / 2 + 1 unique components of the DFT of a real-valued signal. If
fft_length is not provided, it is computed from the size of the inner-most dimension of
fft_length = 2 * (inner - 1)). If the FFT length used to compute
input is odd, it should be provided since it cannot be inferred properly.
Along the axis
IRFFT is computed on, if
fft_length / 2 + 1 is smaller than the corresponding dimension of
input, the dimension is cropped. If it is larger, the dimension is padded with zeros.
