% Storage true_traj = zeros(1,T); meas_traj = zeros(1,T); est_traj = zeros(1,T); % Noise parameters process_noise_pos = 0.1

% --- Update --- x_est = x_pred + K * (z - H * x_pred); P_est = (eye(2) - K * H) * P_pred;

% Matrices F = [1 dt; 0 1]; % state transition H = [1 0]; % we measure only position Q = [process_noise_pos^2 0; 0 process_noise_vel^2]; R = meas_noise_pos^2;
