Dear all,

I'm trying to understand how to use D3 code in order to calculate the 
third-order expansion coefficients.
I ran the example13 provided in PHonon package, however I can't figure 
how to compute the C_{x,y,z} tensor components, B_ and I_ .
Can someone provide some references about since?

Thank you,

                               Éric.
