Kernel-Density-Estimator

基于微分器的PID控制，是自动控制的重要组成部分，有着广泛的应用。(Differentiator-based PID control, automatic control is an important part, has a wide range of applications.)

matlab源程序，可以仿真出来经典的BA无标度网络模型(Matlab source, can be simulated classic BA scale-free network model)

说明：  无迹卡尔曼滤波在目标跟踪中的应用MATLAB仿真(Application of untracked Calman filter in target tracking)

matlab设计小数延时滤波器：滤波器长度,期望延迟量可调整(matlab design fractional delay filter: filter length, adjustable delay expected)

说明：  粒子群算法（PSO）整定pid控制参数，比传统Z-N整定方法要好，内附matlab程序与simulink模型(Particle swarm optimization (PSO) is better than traditional Z-N tuning method in tuning PID control parameters. It includes matlab program and Simulink model.)

Code for PPG signal to estimate the HR of subjects doing intense exercises

绘制任何阵列天线的三维方向图,input_sideline16是一个16单元的线阵，里面是各个单元的位置、幅度、相位信息，先运行这个文件，再运行UNtitle5，就可以画出其二维、三维方向图；同理，自己可以写出任何阵列的信息，然后用UNtitle5画出其方向图。(draw the pattern of the antenna)

说明：  基于主成分分析(PCA)的人脸识别系统。(Based on principal component analysis (PCA) of face recognition systems.)

去趋势波动分析，用于信号分析，可以用于信号去噪，检测信号序列的相关性，内有源码及参考资料一篇(DFA analysis is used to analysis the signal.besides,it can also be used to test the conssitency of the input signal series.)

这两个代码是用贝努利法求方程的最大实根和最小实根，方程只要是标准形式输入参数就可以调用此MATLAB函数(These two functions which are writtern by Matlab can solve out the max and min root through the Benvli method.)
