An implementation of Unscented Kalman Filter for nonlinear state estimation. (Nonlinear 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. The idea is to produce several sampling points (Sigma points) around the current state estimate based on its covariance. Then, propagating these points through the nonlinear map to get more accurate estimation of the mean and covariance of the mapping results. In this way, it avoids the need to calculate the Jacobian, hence incurs only the similar computation load as the EKF. For tutorial purpose, this code implements a simplified version of UKF formulation, where we assume both the process and measurement noises are additive to avoid augment of state and a)

主要是串口数据的收发！ 写了一个GUI界面，包括一些常用的控件，文件的读写，出错的简单处理，弹出对话框等 可能还有一些错误，欢迎拍砖！ 调试在matlab7.0.4上通过！(Mainly to send and receive serial data! Wrote a GUI interface, including some commonly used control, file read and write, a simple error handling, pop-up dialog boxes, etc. There may be some mistakes, please Paizhuan! Debugging in matlab7.0.4 adopted!)
