Interface KalmanEstimation

All Known Implementing Classes:
KalmanModel, SemiAnalyticalKalmanModel, SemiAnalyticalUnscentedKalmanModel, UnscentedKalmanModel
public interface KalmanEstimation
Interface for accessing Kalman filter estimations. The "physical" term used to characterize the states and matrices is used per opposition to the "normalized" states and matrices used to perform the computation.
