function call
r = h_absent(h: ndarray,group : dict, mag : bool)
Variable | Type | Description |
---|---|---|
h | ndarray; dtype = int32; shape = : | Reflection index. Shape = 3 + n, where n is the number of propagation vectors. |
group | dict | Space group. It must be a dictionary of type spg_type or superspacegroup_type. It can be generated with the function set_spacegroup. |
r | tuple | The tuple returned by the function. r[0] : int, error code. If non-zero, an error has occurred. r[1] : str, error message. r[2]: bool; True if reflection is absent, False otherwise. |
