In this guide, we've introduced the basics of the Kalman filter and provided MATLAB examples to help you get started. The Kalman filter is a powerful tool for estimating the state of a system from noisy measurements, and it has a wide range of applications in navigation, control systems, and signal processing. % Initialize the state and covariance x0 =

% Run the Kalman filter x_est = zeros(2, length(t)); P_est = zeros(2, 2, length(t)); for i = 1:length(t) if i == 1 x_est(:, i) = x0; P_est(:, :, i) = P0; else % Prediction x_pred = A*x_est(:, i-1); P_pred = A*P_est(:, :, i-1)*A' + Q; % Measurement update z = y(i); K = P_pred*H'*inv(H*P_pred*H' + R); x_est(:, i) = x_pred + K*(z - H*x_pred); P_est(:, :, i) = P_pred - K*H*P_pred; end end % initial covariance In this guide

% Generate some measurements t = 0:dt:10; x_true = sin(t); y = x_true + 0.1*randn(size(t));

% Plot the results plot(t, x_true, 'b', t, x_est(1, :), 'r'); xlabel('Time'); ylabel('Position'); legend('True', 'Estimated');
