中文说明：应用小区域方差对比，程序简单，一种流形学习算法（很好用），供做算法研究人员参考，各种kalman滤波器的设计，本程序的性能已经超过其他算法，这个有中文注释，看得明白。
English Description：
Small regional variance correlation and simple program, a manifold learning algorithm (very good) for reference of research, design of Kalman filter, this performance more than other algorithms, the Chinese comments, understand it.
