%% 1. SIMULATE THE REAL WORLD dt = 0.1; % Time step (seconds) t = 0:dt:10; % Time vector (10 seconds) N = length(t); % Number of time steps

git clone https://github.com/balzer82/Kalman MATLAB.zip If you are an instructor, create a ZIP of the above scripts and host it. Here is a simple batch script (Windows) or bash (Mac/Linux) to create a zip: Velocity] x_est = [0

% Storage for results stored_x = zeros(2, N); stored_P = zeros(2, 2, N); % Initial guess: position 0

% Measurement update z = measurements(k); y = z - H * x_pred; S = H * P_pred * H' + R; K = P_pred * H' / S; velocity 0 P_est = [100

rmse_raw = sqrt(mean((measurements - true_pos).^2)); rmse_kalman = sqrt(mean((stored_x(1,:) - true_pos).^2)); fprintf('Raw sensor RMSE: %.3f m\n', rmse_raw); fprintf('Kalman filter RMSE: %.3f m\n', rmse_kalman);

%% 2. KALMAN FILTER INITIALIZATION % State vector: [Position; Velocity] x_est = [0; 0]; % Initial guess: position 0, velocity 0 P_est = [100, 0; % High uncertainty in initial position 0, 10]; % Lower uncertainty in initial velocity

% State transition with known input (gravity) % x(k+1) = F x(k) + B u(k) F = [1, dt; 0, 1]; B = [0.5*dt^2; dt]; % Control input matrix for acceleration u = g; % Control input (gravity)
