Fonction set_global_backend - module scipy.fft

Signature de la fonction set_global_backend

def set_global_backend(backend) 

Description

set_global_backend.__doc__

Sets the global fft backend

    The global backend has higher priority than registered backends, but lower
    priority than context-specific backends set with `set_backend`.

    Parameters
    ----------
    backend : {object, 'scipy'}
        The backend to use.
        Can either be a ``str`` containing the name of a known backend
        {'scipy'} or an object that implements the uarray protocol.

    Raises
    ------
    ValueError: If the backend does not implement ``numpy.scipy.fft``.

    Notes
    -----
    This will overwrite the previously set global backend, which, by default, is
    the SciPy implementation.

    Examples
    --------
    We can set the global fft backend:

    >>> from scipy.fft import fft, set_global_backend
    >>> set_global_backend("scipy")  # Sets global backend. "scipy" is the default backend.
    >>> fft([1])  # Calls the global backend
    array([1.+0.j])
