@Operator(group="signal") public final class Irfft extends PrimitiveOp implements Operand<Float>
Computes the inverse 1-dimensional discrete Fourier transform of a real-valued signal over the inner-most dimension of `input`.
The inner-most dimension of `input` is assumed to be the result of `RFFT`: the `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 `input` (`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 `signal.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.
