# irfft2

scipy.fft.irfft2(x, s=None, axes=(-2, -1), norm=None, overwrite_x=False, workers=None, *, plan=None)

  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()`. See `fft` 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.

      Added in version 1.5.0.

  Returns:
    outndarray

      The result of the inverse real 2-D FFT.

  Notes

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