CLUSTER-FORMATION

说明：  简单眼图，适用于初学者，仅仅是简单的代码，高手请绕道(Simple eye)

利用差值法根据已经给定的多个数据点画图 得到五个图形(Using difference method has been given under a number of data points are five graphic drawing)

MATLAB程序代码，对人数进行统计，对图像灰度进行处理。(MATLAB program code, statistics on the number, carries on processing to the image gray.)

Pass the Images Through Optics -- Use a Gaussian "Aperture Function" This code segement can use a measured aperture function just as easily - simply replace the next five lines by "load measured_aperture" where measured_aperture is the measured function strored in ASCII and the data stored in the file measured_aperture.mat is a MATLAB .mat file that contains the matrix apfunction. (in MATLAB type "help load" for how to use load and look at the c and fortran code that shows how to read and write MATLAB .mat files). (Note: When the Point Spread Function is Gaussian, then so is the Aperture function) To simulate the effect of the tracker optics, each of the movie frames is now blurred using a 2-D FFT (Fast Fourier Transform). The first frame of the resulting image is shown in Figure 1.

说明：  适合于数学建模的系统教程,介绍了系统模型及转换,系统时间响应和动态仿真等,并配合程序设计(Suitable for mathematical modeling of systems curricula, introduce the system model and conversion, system time response and dynamic simulation and so on, and in line with the program design)

说明：  岭回归的matla源程序，主要用于解决无法求逆或需要更好的解时所用的(Ridge regression matla source, mainly used to solve the inverse can not be a better solution or need to use when)

电力系统最优潮流计算，可以用来确定最优潮流，计算网损等(Optimal power flow calculation can be used to determine the optimal power flow, and other computing net loss)

通信学中的QAM调制，这是一个比较经典的程序(QAM in communications )

偏最小二乘程序,快速拟合数据，等到一个比较理想的估计值。(Partial least squares procedure, fast fit the data, until a more satisfactory estimate.)

演变过程 自抗扰控制器自PID控制器演变过来，采取了PID误差反馈控制的核心理念。传统PID控制直接引取输出于参考输入做差作为控制信号，导致出现响应快速性与超调性的矛盾出现。(In the process of evolution, ADRC evolves from PID controller and adopts the core idea of PID error feedback control. Traditional PID control directly draws the output from the reference input as a control signal, which leads to the contradiction between response speed and overshoot.)
