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

% Initial guess x_est = 20; % initial estimate (wrong on purpose) P_est = 5; % initial uncertainty (high)

for k = 1:T % True motion true_pos = true_pos + true_vel * dt; true_traj(k) = true_pos; It sounds complex, but at its heart, it

If you are an engineering student, a robotics hobbyist, or a data scientist venturing into signal processing, you have likely heard of the Kalman filter . It sounds complex, but at its heart, it is a brilliant algorithm for estimating the state of a dynamic system from noisy measurements.
