Fonction ihfft2 - module scipy.fft

Signature de la fonction ihfft2

def ihfft2(x, s=None, axes=(-2, -1), norm=None, overwrite_x=False, workers=None, *, plan=None) 

Description

help(scipy.fft.ihfft2)

Compute the 2-D inverse FFT of a real spectrum.

Parameters
----------
x : array_like
    The input array
s : sequence of ints, optional
    Shape of the real input to the inverse FFT.
axes : sequence 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_x : bool, optional
    If True, the contents of `x` can be destroyed; the default is False.
    See :func:`fft` for more details.
workers : int, optional
    Maximum number of workers to use for parallel computation. If negative,
    the value wraps around from ``os.cpu_count()``.
    See :func:`~scipy.fft.fft` for more details.
plan : object, optional
    This argument is reserved for passing in a precomputed plan provided
    by downstream FFT vendors. It is currently not used in SciPy.

    .. versionadded:: 1.5.0

Returns
-------
out : ndarray
    The result of the inverse real 2-D FFT.

See Also
--------
ihfftn : Compute the inverse of the N-D FFT of Hermitian input.

Notes
-----
This is really `ihfftn` with different defaults.
For more details see `ihfftn`.
