最小均方自适应滤波 可用于系统辨识 预测编码 谱分析 噪声消除(LMS adaptive filter can be used to identify predictive coding system to eliminate noise spectral analysis)

说明：  卡尔曼滤波程序，基于卡尔曼的目标跟踪演示程序(kf filter)

利用游程编码和哈弗曼编码实现灰色图片的压缩和解码，压缩比可达15倍(Using run-length encoding and Hafu Man Coding and decoding of gray image compression, the compression ratio up to 15 times)

普通的PID控制，程序正确，下载就能用，只需要改PID控制的三个参数即可(Normal PID control, the program correctly, you can use to download, just change the parameters of PID control can be of three)

介质层间反射系数及其透射系数的求解，此处是二分之一匹配层结构(Dielectric layer between the reflection coefficient and transmission coefficient of the solution)

说明：  井筒参数的计算，盐穴储气库中的注采井的井筒的相关参数计算(Wellbore parameter calculation, salt cavern gas storage in the wellbore injection wells calculate the relevant parameters)

this code extract instantaneous frequency of signal

说明：  matlab中一些重要的课件和资料，比较有用啊！(matlab courseware and some important information, more useful ah!)
