scipy.fft.irfft2

scipy.fft.irfft2(x, s=None, axes=(-2, -1), norm=None, overwrite_x=False, workers=None)[source]

Compute the 2-D inverse FFT of a real array.

Parameters
xarray_like

The input array

ssequence of ints, optional

Shape of the real output to the inverse FFT.

axessequence of ints, optional

The axes over which to compute the inverse fft. Default is the last two axes.

norm{None, “ortho”}, optional

Normalization mode (see fft). Default is None.

overwrite_xbool, optional

If True, the contents of x can be destroyed; the default is False. See fft for more details.

workersint, optional

Maximum number of workers to use for parallel computation. If negative, the value wraps around from os.cpu_count(). See fft for more details.

Returns
outndarray

The result of the inverse real 2-D FFT.

irfftn

Compute the inverse of the N-D FFT of real input.

Notes

This is really irfftn with different defaults. For more details see irfftn.
