An implementation of EKF-based SLAM with range-bearing sensors, odometry, a full 6D robot pose, and 3D landmarks.
The main method is "processActionObservation" which processes pairs of action/observation. The state vector comprises: 3D robot position, a quaternion for its attitude, and the 3D landmarks in the map.
The following Wiki page describes an front-end application based on this class: http://www.mrpt.org/Application:kf-slam
For the theory behind this implementation, see the technical report in: http://www.mrpt.org/6D-SLAM

If applicable to the given problem, this method implements the inverse observation model needed to extend the "map" with a new "element".
The uncertainty in the new map feature comes from two parts: one from the vehicle uncertainty (through the out_dyn_dxv Jacobian), and another from the uncertainty in the observation itself. By default, out_use_dyn_dhn_jacobian=true on call, and if it's left at "true", the base KalmanFilter class will compute the uncertainty of the landmark relative position from out_dyn_dhn. Only in some problems (e.g. MonoSLAM), it'll be needed for the application to directly return the covariance matrix out_dyn_dhn_R_dyn_dhnT, which is the equivalent to:
\f$ \frac{\partial y_n}{\partial h_n} R \frac{\partial
y_n}{\partial h_n}^\top y_n=y(x,z_n) @_fakenlF \times V \frac{\partial y_n}{\partial x_v} @_fakenlF \times O \frac{\partial y_n}{\partial h_n}
