The Kalman Filter is a recursive mathematical algorithm that estimates the state of a system from a series of incomplete and noisy measurements. In MATLAB, it is widely used for applications ranging from to audio noise reduction . 🚀 The Essence of the Kalman Filter The filter works in a two-step cycle: Predict and Update . % Update estimate with measurement y_tilde = z_meas(k)
