(a, s=None, axes=(-2, -1), norm=None)[source]¶ 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
New in version 1.10.0.
Normalization mode (see
numpy.fft
). Default is None.Returns: out : ndarray
The result of the inverse real 2-D FFT.
