NEF is newly designed framework for nonlinear state estimation of discrete dynamical systems. The aim of this framework is to facilitate implementation, testing and use of various nonlinear state estimation methods. The main strength of the framework is its versatility due to the possibility of either structural or probabilistic description of the problem. As the toolbox is designed on the object oriented basis, further adding of user-specified nonlinear estimation algorithms is extremely easy.

This new toolbox should overcome following deficiencies of the framework which constitues base of the NFTools:
- It should made it possible to describe system not only by difference equations. The description by probability density functions is also supported.
- It should support the specification of time-varying systems.

The key element of the new design is the unified description of random variables. It also uses the new MATLAB® class system.
