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 - fftfor more details.
- workersint, optional
- Maximum number of workers to use for parallel computation. If negative, the value wraps around from - os.cpu_count(). See- fftfor 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. - Added in version 1.5.0. 
 
- Returns:
- outndarray
- The result of the inverse real 2-D FFT.
