x_est = [0; 0]; P = [100 0; 0 100]; % High initial uncertainty

%% Initialize Kalman Filter % State vector: [position; velocity] x_est = [0; 10]; % Initial guess (position, velocity) P = [1 0; 0 1]; % Initial uncertainty covariance %% Plot results figure('Position', [100 100 800 600]);

K_history(k) = K(1); P_history(k) = P(1,1); end

With MATLAB, you can start simple—tracking a position in 1D—and gradually move to 2D tracking, then to EKF for a mobile robot. The examples provided give you a working foundation. Experiment by changing noise levels, initial conditions, and tuning parameters. The Kalman filter is not just a tool; it's a way of thinking about fusing information in the presence of uncertainty. The Kalman filter is not just a tool;

K_history = zeros(50, 1); P_history = zeros(50, 1);
