Kalman Filter for Beginners: A Practical Guide with MATLAB Examples

Chapter 5: Nonlinearity and the Extended Kalman Filter (EKF)

• A teaser for the next level (though the "Beginner" book focuses mostly on linear KF).

where x(k) is the state of the system at time k, A is the state transition matrix, B is the input matrix, u(k) is the input to the system, and w(k) is the process noise.

for k = 1:length(z) % Predict x = F * x; P = F * P * F' + Q;
