Dispatched C++ function(s).

[1] (n: [int, len = 3])
  -> bool

Check if an index \(\mathbf{n}\) is valid, i.e. corresponds to a unit cell/lattice point in the supercell.

Parameters:

n[int, len = 3]

Index \(\mathbf{n}\) to check.

Returns:

bool

True if \(0 \leq n_i < N_i \; \forall i\), false otherwise.
