说明：  用matlab开发的运动模糊复原程序，包括运动参数的估计、维纳滤波器的源代码(Development of the motion blur with matlab recovery procedures, including the motion parameters estimation, Wiener filter source code)

说明：  matlab的图像命令，，有详尽的函数说明，，便于查询(matlab image order, a detailed function description, easy to check)

it is a code of dispersion relation of one dimension phononic crystal

主要对扩展卡尔曼滤波（EKF）、无迹卡尔曼滤波（UKF）及改进无迹卡尔曼滤波（MAUKF）算法进行研究，研究了三种算法的基本原理和各自的特点。其中扩展卡尔曼滤波器是将卡尔曼滤波器局部线性化，其算法简单，计算量小，适用于弱非线性、高斯环境。无迹卡尔曼滤波器是用一系列确定样本来逼近状态的后验概率密度。改进无迹卡尔曼滤波算法在UKF的基础上引入衰减因子。(Improved Kalman filtering algorithm)

说明：  采用MATLAB语言编写的基于蒙特卡罗法的复杂系统可靠性仿真威布尔分布，使用过程中，可以根据具体的情况，进行相应参数的修改。(The reliability simulation Weibull distribution of complex system based on Monte Carlo method is written in MATLAB language. in the process of using, the corresponding parameters can be modified according to the specific situation.)
