Parameters fixed_grid_number : int Grid point of q0 mesh : array_like Mesh numbers dtype='intc' shape=(3,) rotations : array_like Rotation matrices in real space. Note that those in reciprocal space mean these matrices transposed (local terminology). dtype='intc' shape=(n_rot, 3, 3) is_time_reversal : bool Inversion symemtry is added if it doesn't exist. swappable : bool q1 and q2 can be swapped. By this number of triplets decreases. """
