cirq.is_special_orthogonal

Determines if a matrix is approximately special orthogonal.

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

A matrix is special orthogonal if it is square and real and its transpose is its inverse and its determinant is one.

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

Whether the matrix is special orthogonal within the given tolerance.
