Fonction chebyshev - module scipy.spatial.distance

Signature de la fonction chebyshev

def chebyshev(u, v, w=None) 

Description

chebyshev.__doc__

    Compute the Chebyshev distance.

    Computes the Chebyshev distance between two 1-D arrays `u` and `v`,
    which is defined as

    .. math::

       \max_i {|u_i-v_i|}.

    Parameters
    ----------
    u : (N,) array_like
        Input vector.
    v : (N,) array_like
        Input vector.
    w : (N,) array_like, optional
        Unused, as 'max' is a weightless operation. Here for API consistency.

    Returns
    -------
    chebyshev : double
        The Chebyshev distance between vectors `u` and `v`.

    Examples
    --------
    >>> from scipy.spatial import distance
    >>> distance.chebyshev([1, 0, 0], [0, 1, 0])
    1
    >>> distance.chebyshev([1, 1, 0], [0, 1, 0])
    1
