pyscfad.pbc.gto.cell.Cell.get_Gv

Cell.get_Gv(mesh=None, **kwargs)

Calculate three-dimensional G-vectors for the cell; see MH (3.8).

Indices along each direction go as [0…N-1, -N…-1] to follow FFT convention.

Args:

cell : instance of Cell

Returns:

Gv(ngrids, 3) ndarray of floats

The array of G-vectors.
