[Pw_forum] Format of dynamical matrices

[Raji Abdulrafiu]

Thanks Stefano. However, personally,  I am not yet clear about your
explanation regarding the dynamical matrices. Please explain in clear terms
what those zeros in  second , fourth and sixth columns after the  'Dynamical
Matrix in Cartesian axes' stand for. Also the zeros in similar columns after
the "Diagonalizing the dynamical matrix. What do they correspond to?

Thank you very much.
