obj: Lattice | Structure | Prim | Prim | Configuration | ConfigurationWithProperties,

)

Get lattice vectors from a lattice, structure, configuration, or prim

Parameters:

obj (CasmObjectWithLattice) – A lattice, structure, configuration, or prim.

Returns:

lattice – The lattice vectors as columns (i.e. a == lattice[:,0], b == lattice[:,1], c == lattice[:,2]).

Return type:

np.ndarray[np.float64[3,3]]
