A good complement of linear Kalman filter in Simulink: http://www.mathworks.com/matlabcentral/fileexchange/46407-linear-kalman-filter-in-simulink

The observation function h is a linear function. Can it be a linear function for EKF?

Nice commentgs. Awful numerics. Never multiply by inv(S). It's unstable and slow.

Replace

K = P*H'*inv(S)

with

K = (P*H')/S

Very nice tutorial.
(only the magenta plot is a little confusing at the first sight, it's not a part of the EKF)

It is easy to improve for another signals

BE CAREFUL! It may be a good demo, but it clears all your variables and closes all your figures without asking you! Just imagine you are working for many hours on some important topic and you are just about to present or save your result, so trying this tutorial at this point will be fatal for you! I can't understand why someone does "clear all; close all;" on a foreign machine!!! Bad style!
