cirq.is_unitary(
    matrix: np.ndarray, *, rtol: float = 1e-05, atol: float = 1e-08
) -> bool

A matrix is unitary if it's square and its adjoint is its inverse.

Args
`matrix`	The matrix to check.
`rtol`	The per-matrix-entry relative tolerance on equality.
`atol`	The per-matrix-entry absolute tolerance on equality.

Returns
Whether the matrix is unitary within the given tolerance.
