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
