Dear MPB-users,
I have a question concerning the built-in commands (compute-group-velocities)
and (compute-group-velocity-component direction). For photonic crystals and
photonic crystal line-defect structures
(run-te display-group-velocities) works fine, but for the two lower
level functions listed above I couldn't have found a way to make them
run. Regarding the link below, can anyone send me a sample code that pass them
into a function?

In a triangular lattice line defect PhCW, if I want to calculate the “X”
component (in cartesian) of group velocity, can I write the direction of
group-velocity-component (vector3 0.866 0.866 0) ? (cartesian->reciprocal
(vector3 1 0 0)) ==> (0.866 0.866 0)
Thank you very much.
