扩展卡尔曼滤波和unsented卡尔曼滤MATLAB工具箱，很实用(Unsented extended Kalman filtering and Kalman filter MATLAB toolbox, very practical)

Fading envelope simulator

函数dB=PSNR(F,G),返回图像F相对于图像G的信噪比峰值.用于全息图后期处理中的参考.测试通过(Based of the formular dB=PSNR(F,G),it returns peak signal-to-noise ratio (dB) of image F with respect to G.)

最小凸包的实现程序，用matlab编程的源码，使用的不是matlab自带的凸包函数，而是自己编的，有详细的运算流程图，一看就懂，main为主程序，ConvexHull为函数。(ConvexHull，matlab，with Flow Diagram)

用于图像压缩，并同时对图像进行加密，减少存储空间(In this project we implemented an Image Compression and Encryption algorithm from the reserach paper "Novel Image Compression-encryption hybrid algorithm based on a key-controlled measurement matrix in compressive sensing" by Nanrun Zhou, Aidi Zhang, Fen Zheng, Lihua Gong.)

一个基于matlab的harris角点图像配准程序，运行效果良好，虽然存在误匹配，但很值得借鉴。(A harris corner points based on matlab for image registration procedures, running well, although there are false matches, but it is worth learning from.)

IPHLPAPI.dll win7 连网无法启动matlab(IPHLPAPI.dll win7 networking can not start matlab)

考虑输入双输出系统，输入量均为方差为1的互不相交白噪声，测量噪声采用方差为0.1的互不相交白噪声(Consider input dual-output system, enter the amount of all variance disjoint white noise, measurement noise variance was used to the white noise of 0.1 disjoint)
