In addition to the EKF and UKF code, it may be helpful to provide more detail regarding the applications and benefits of these algorithms. For example, the extended Kalman filter (EKF) is a widely used method for state estimation in nonlinear systems. It can be particularly useful in situations where the underlying model is nonlinear and the state is only partially observable. The unscented Kalman filter (UKF) is a variant of the EKF that approximates the probability distribution of the state variables using a set of deterministic sampling points, known as sigma points. This approach can be more accurate than the EKF in certain scenarios, such as those with highly nonlinear models or non-Gaussian distributions. By including such additional information, readers may gain a deeper understanding of the EKF and UKF algorithms and their potential applications in various fields.
