scipy.fft.rfft2#
- scipy.fft.rfft2(x, s=None, axes=(- 2, - 1), norm=None, overwrite_x=False, workers=None, *, plan=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{“backward”, “ortho”, “forward”}, optional
Normalization mode (see
fft
). Default is “backward”.- 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()
. Seefft
for more details.- planobject, optional
This argument is reserved for passing in a precomputed plan provided by downstream FFT vendors. It is currently not used in SciPy.
New in version 1.5.0.
- Returns
- outndarray
The result of the real 2-D FFT.
