三相PWM叠加三次谐波控制Simulink仿真，另加一滤波器观看PWM经过低通滤波后的波形，适合电力电子初学者(Superposition of three harmonic three-phase PWM control Simulink simulation, plus a watch PWM filter through after the low-pass wave filter for power electronics for beginners)

matlab中的mapminmax函数，可以直接使用(matlab' s mapminmax function, can be used directly)

好用的随机森林回归（RFR），也可用与分类。基于以编译的mex84，可实现bias-correction。回归预测精度较高(applicable random forrest regression，can also be used for classification。Regress with bias-correction 。can achieve high accuracy)

K均值聚类，输入聚类前的点集以及阈值，输出最后各个分类的中心点(K-means clustering, the input point set before clustering and threshold, output the final classification of the center of each)

通过matlab调用xfoil程序，对翼型升阻力力矩进行计算，并将计算结果生成结果文件，程序中对三种翼型进行了计算，用户可根据需要删减或复制程序的相同部分即可(Xfoil by calling the same part of matlab procedures, the airfoil lift and drag torque is calculated, and the calculated results file is generated, the program for the three airfoils were calculated, the user can cut or copy the program as needed to)

智能洗衣机的模糊控制法则及隶属函数，可载入模块中进行使用(Fuzzy control rules and membership functions of the smart washing machines, you can load the module using the)

局部线性降维方法LLE 用于高维空间数据的降维处理(Local linear dimension reduction methods for high dimensional data LLE dimensionality reduction process)

使用matlab做的离散时间单位冲激响应(Discrete-time unit impulse response)

bootstrap matlab 程序,内含4个文件(bootstrap matlab programe，there are four files)

主要介绍在matlab中如何使用好绘图的函数，以及一些例子(Mainly introduces how to use the matlab function better graphics, as well as some examples)
