MATLAB软件的差值与拟合的思想简介和MATLAB的实现，适合初学者参考(MATLAB software and fitting the difference between the ideological profile and MATLAB implementation of reference for beginners)

基于非线性动力系统的无迹卡尔曼滤波matlab程序(onlinear state estimation is a challenge problem. The well-known Kalman Filter is only suitable for linear systems. The Extended Kalman Filter (EKF) has become a standarded formulation for nonlinear state estimation. However, it may cause significant error for highly nonlinear systems because of the propagation of uncertainty through the nonlinear system. The Unscented Kalman Filter (UKF) is a novel development in the field)
