numpy.fft.irfft2 — NumPy v1.13 Manual (original) (raw)

numpy.fft. irfft2(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.
