xnn.common.models.pme.mesh_wavevectors# xnn.common.models.pme.mesh_wavevectors(cell, mesh)[source]# The wave vectors of a mesh in FFT order: 2 pi times the Miller indices dotted with the reciprocal vectors. Parameters: cell (Tensor) – Lattice vectors as rows (3, 3). mesh (list of int) – Mesh dimensions (K_1, K_2, K_3). Returns: k of shape (K_1, K_2, K_3, 3) and |k|^2 of shape (K_1, K_2, K_3), in 1/Angstrom. Return type: tuple of Tensor
