void BetweenFactorRot3(const sym::Rot3<Scalar> &a, const sym::Rot3<Scalar> &b, const sym::Rot3<Scalar> &a_T_b, const Eigen::Matrix<Scalar, 3, 3> &sqrt_info, const Scalar epsilon, Eigen::Matrix<Scalar, 3, 1> *const res = nullptr, Eigen::Matrix<Scalar, 3, 6> *const jacobian = nullptr, Eigen::Matrix<Scalar, 6, 6> *const hessian = nullptr, Eigen::Matrix<Scalar, 6, 1> *const rhs = nullptr)

Residual that penalizes the difference between between(a, b) and a_T_b.

In vector space terms that would be: (b - a) - a_T_b

In lie group terms: local_coordinates(a_T_b, between(a, b)) to_tangent(compose(inverse(a_T_b), compose(inverse(a), b)))

Args: sqrt_info: Square root information matrix to whiten residual. This can be computed from a covariance matrix as the cholesky decomposition of the inverse. In the case of a diagonal it will contain 1/sigma values. Must match the tangent dim. jacobian: (3x6) jacobian of res wrt args a (3), b (3) hessian: (6x6) Gauss-Newton hessian for args a (3), b (3) rhs: (6x1) Gauss-Newton rhs for args a (3), b (3)
