Fonction hfft2 - module scipy.fft

Signature de la fonction hfft2

def hfft2(x, s=None, axes=(-2, -1), norm=None, overwrite_x=False, workers=None, *, plan=None) 

Description

help(scipy.fft.hfft2)

Compute the 2-D FFT of a Hermitian complex array.

Parameters
----------
x : array
    Input array, taken to be Hermitian complex.
s : sequence of ints, optional
    Shape of the real output.
axes : sequence of ints, optional
    Axes over which to compute the FFT.
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 `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 real result of the 2-D Hermitian complex real FFT.

See Also
--------
hfftn : Compute the N-D discrete Fourier Transform for Hermitian
        complex input.

Notes
-----
This is really just `hfftn` with different default behavior.
For more details see `hfftn`.
