CSL#

atomman_gb.csl.get_csl(R: numpy.ndarray[Any, numpy.dtype[numpy._typing._generic_alias.ScalarType]], sigma: int) → numpy.ndarray[Any, numpy.dtype[numpy._typing._generic_alias.ScalarType]]#

Return CSL from rotation matrix R which transform lattice-1 to lattice-2.

Parameters

  • R (array, (3, 3)) – Rotation matrix in fractional coordinates

  • sigma (int) – Least positive integer such that sigma * R and sigma * np.linalg.inv(R) are integer matrices.

Returns

csl – Intersection of lattice-1 and lattice-2

Return type

array, (3, 3)
