The betweenness calculation seems fine for me for this network; i.e.,
the maximum betweenness is 3641.928 and the minimum is zero. What are
your results?

This is not implemented directly in igraph, but it's fairly simple (at
least if you are thinking about the assortativity coefficient as defined
by Newman). This is calculated in Python as follows:

I guess it's not too complicated to translate this back to C.
