where x_est is the state estimate, P_est is the estimate covariance, Q is the process noise covariance, and R is the measurement noise covariance.

MATLAB EKF tip: implement Jacobians analytically or compute numerically; iterate predict and update similarly to linear case. Update Step: Kalman Gain
The early chapters focus on linear systems. Kim explains the "Magic Five" equations of the Kalman Filter (Predict Step: State and Covariance; Update Step: Kalman Gain, State Update, Covariance Update). He strips away the noise to show the elegance of the algorithm.
