The toolbox provides the methods linearization, Unscented Transform and Monte Carlo for uncertainty propagation. Since the code for all three variants is essentially equivalent and compact, concepts as the Extended Kalman Filter and the Unscented Kalman Filter are easily implemented following the same approach as for the already introduced uncertainty quantification.
