scipy.fft.irfft2#
- scipy.fft.irfft2(x, s=None, axes=(- 2, - 1), norm=None, overwrite_x=False, workers=None, *, plan=None)[source]#
Computes the inverse of
rfft2
- 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{“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 inverse real 2-D FFT.
