SEP_LEACH_HEED(code)

说明：  整参数估计，是参数估计理论中的重要内容。(The whole parameter estimation, parameter estimation is an important part of the theory.)

非常好的matlab增量式式PID控制算法(Very good matlab incremental PID control algorithm)

低通滤波器设计 绘制各种响应曲线 绘制输入信号曲线 绘制滤波后效果曲线(LPF DESIGN ALL CURVES INPUT SIGNAL OUTPUT SIGNAL)

HHT变换的EMD方法和希尔伯特谱的一些源程序，以及一些实例数据(HHT transform the EMD method and Hilbert spectrum of some of the source, and some examples of data)

任意几何形状和阵元指向性的传感器阵列优化波束形成方法(Arbitrary geometry and element directivity optimization of the sensor array beamforming method)

DS-CDMA仿真源程序，内附详细说明文档，适合初学者(DS-CDMA simulation source code, containing detailed documentation, suitable for beginners)

基于隐马尔科夫模型HMM的人脸识别程序，使用Matlab编写，提取的人脸识别特征为DCT系数(it is face detection codes based on HMM Model ，you can run iton Matlab，the feature from face is DCT)

说明：  迭代法 迭代式阈值选取的基本思路是:首先根据图像中物体的灰度分布情况， 选取一个近似阈值作为初始阈值(Iterative threshold selected basic idea is: First, the gray-scale distribution of objects in the image, select an approximate threshold as initial threshold)

good resource code for people to get better performance.such as ssim,rmse etc.

完备工具包，在原工具包中添加了io.m/extr.m，instfreq.m(Complete toolkit, in the original kit added io.m/extr.m, instfreq.m)
