基于UWT变换的去噪，利用的是硬阈值来设置阈值门限的(UWT transform based denoising, using the hard threshold to set the threshold value threshold)

支持向量机的MATlab工具包，很有用，也很复杂，没有功底的，就别下了(SVM MATlab kit, useful, and very complex, there is no foundation for, do not down)

this code used for stephest algorithm

EKF仿真，用于陀螺漂移误差仿真，较适合于初学者使用学习(EKF simulation for gyro drift error simulation, more suitable for beginners learning to use)
