# scipy.fft.rfft2¶

scipy.fft.rfft2(x, s=None, axes=(-2, -1), norm=None, overwrite_x=False, workers=None)[source]

Compute the 2-D FFT of a real array.

Parameters
xarray

Input array, taken to be real.

ssequence of ints, optional

Shape of the FFT.

axessequence of ints, optional

Axes over which to compute the FFT.

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 real 2-D FFT.

rfftn

Compute the N-D discrete Fourier Transform for real input.

Notes

This is really just rfftn with different default behavior. For more details see rfftn.
