Detailed Description

Class representing all Rauch-Tung-Striebel backward filters.

This is a class representing the Rauch-Tung-Striebel backward filter. It is a backward filter in which the Posterior density is represented by a Gaussian density. Rauch-Tung-Striebel backward filter are only applicable to continuous systems.

The system of updating the Posterior density is implemented in this base class.
