This function computes the Rauch-Tung-Striebel smoother.
1 | rtsSmoother(M, P, A, Q)
|
M |
An N x K matrix of K mean estimates from the Kalman Filter |
P |
An N x N x K cube length K with N x N state covariances matrices from the Kalman Filter |
A |
An N x N state transition matrix (or in the more general case a list of K such matrices; not yet implemented) |
Q |
An N x N noise covariance matrix (or in the more general case a list of K such matrices; not yet implemented) |
This function implements the Rauch-Tung-Striebel smoother algorithm which calculate a “smoothed” sequence from the given Kalman filter output sequence by conditioning all steps to all measurements.
A list with three elements
the smoothed mean sequence,
the smooted state covariance sequence,and
the smoothed gain sequence.
The EKF/UKF Toolbox was written by Simo Särkkä, Jouni Hartikainen, and Arno Solin.
Dirk Eddelbuettel is porting this package to R and C++, and maintaing it.
