  r"""2D real-valued fast Fourier transform.

  Computes the 2-dimensional discrete Fourier transform of a real-valued signal

  over the inner-most 2 dimensions of `input`.

  

  Since the DFT of a real signal is Hermitian-symmetric, `RFFT2D` only returns the

  `fft_length / 2 + 1` unique components of the FFT for the inner-most dimension

  of `output`: the zero-frequency term, followed by the `fft_length / 2`

  positive-frequency terms.

  

  Along each axis `RFFT2D` is computed on, if `fft_length` is smaller than the

  corresponding dimension of `input`, the dimension is cropped. If it is larger,

  the dimension is padded with zeros.

  Args:
    input: A `Tensor`. Must be one of the following types: `float32`, `float64`.
      A float32 tensor.
    fft_length: A `Tensor` of type `int32`.
      An int32 tensor of shape [2]. The FFT length for each dimension.
    Tcomplex: An optional `tf.DType` from: `tf.complex64, tf.complex128`. Defaults to `tf.complex64`.
    name: A name for the operation (optional).

  Returns:
    A `Tensor` of type `Tcomplex`.
