说明：  极限学习机是一类针对单层前馈神经网络设计的机器学习算法，其主要特点是隐含层节点参数可以是随机或人为给定的且不需要调整，学习过程仅需计算输出权重。ELM具有学习效率高和泛化能力强的优点，被广泛应用于分类、回归、聚类、特征学习等问题中。(Extreme learning machine for particle swarm optimization)

说明：  采用罚函数法对约束条件进行处理，利用matlab编程粒子群算法进行优化(Penalty function method is used to deal with the constraint conditions, and MATLAB is used to program particle swarm optimization algorithm)

说明：  1、图像显示：这个代码中制作了比较友好的图像显示功能和函数接口，非常方便客户调用，图像显示制作成控件的模式，带源代码； 2、图像显示平移以及放大缩小：在图像显示代码模块中以及将图像的拖拽、鼠标滚轮控制的放大缩小功能集成好了，提供代码接口，非常好用，可看到源代码学习； 3、文件操作模块：目前代码集成了6种文件的创建读写保存类，分别为：office中的Excel操作，IniFile的操作，LogFile的操作，Spire控件下的Excel操作，Txt文件操作，Xml文件操作(1. Image display: this code makes a friendly image display function and function interface, which is very convenient for customers to call. The image display is made into control mode with source code; 2. Image display translation and zoom in and out: in the image display code module, the image drag and zoom function controlled by mouse wheel are integrated, providing code interface, which is very easy to use and can see the source code learning; 3. File operation module: at present, the code integrates six kinds of file creation, reading, writing and saving classes, including excel operation in office, IniFile operation, logfile operation, excel operation under spire control, TXT file operation, XML file operation.)

experiment equipment: stm32F103 C8T6 Purpose: ADC real-time sampling shows waveforms through an anonymous host computer (virtual oscilloscope) ADC1 and serial 1 dual DMA use to speed up the transfer rate Hardware resources: 1, ADC1 channel 1 (peripheral A1) 2, serial port 1 (baud rate: 500000) Experimental phenomena: The anonymous host computer displays the waveform in real time. The sampling frequency of the ADC is about 1Mhz (the highest value of the single ADC mode has been reached, but the maximum transmission rate of the host computer is about 500000 baud. And only one byte per transfer of 14 bytes is valid (caused by the anonymous transfer protocol). It takes about 2.8ms to transfer once.
