%% Kalman Filter for Beginners - 1D Position Tracking % This example simulates an object moving at a constant velocity. % We will track it using a Kalman Filter.

%% 3. KALMAN FILTER LOOP for k = 1:N % --- PREDICTION STEP --- x_pred = F * x_est; % Predict state P_pred = F * P_est * F' + Q; % Predict covariance

To dive deeper, you should explore the , which includes built-in functions like kalman() for state-space models.
