Data Assimilation Demo

This web-page aims to demonstrate the Kalman Filter with some simple linear toy models. First choose model and data assimilation parameters and then click on "Run assimilation"

Model parameters

The function model should return the state vector at the next time step given the state vector x at the time step n.
