def charpath(D):
    """ Distance based measures

    This function outputs four distance based measures. Characteristic path
    length is the average shortest path length. Node eccentricity is the
    maximal shortest path length between a node and any other node. Network
    radius is the minimum eccentricity, while network diameter is the maximum
    eccentricity.

    Characteristic path length is calculated as the global mean of the
    distance matrix D, not taking into account any 'Infs' but including the
    distances on the main diagonal.
    
    Parameters
    ----------
    D : distance matrix
    
    Returns
    -------
    ecc : eccentricity (for each vertex)
    
    Notes
    -----
    The radius of the graph is min(ecc)
    The diameter of the graph is max(ecc)
        
    See Also
    --------
    charpath_lambda(D) for characteristic path length
