Description:
 def irfft2(a, s=None, axes=(-2, -1), norm=None):
 """ Compute the 2-dimensional inverse FFT of a real array. Parameters a : array_like The input array s : sequence of ints, optional Shape of the inverse FFT. axes : sequence of ints, optional The axes over which to compute the inverse fft. Default is the last two axes. norm : {None, "ortho"}, optional .. versionadded:: 1.10.0 Normalization mode (see `numpy.fft`). Default is None. Returns ------- out : ndarray The result of the inverse real 2-D FFT. See Also -------- irfftn : Compute the inverse of the N-dimensional FFT of real input. Notes ----- This is really `irfftn` with different defaults. For more details see `irfftn`. """
