说明：  对一个二阶模型模型进行脉冲响应辨识，并且通过搭建simulink模型取得了两组输入-输出数据，一组是在有高斯噪声的干扰下获得u1-y3，另外一组是在没有高斯噪声的情况下获得的u1-y1，对这两组数据进行基于haar小波基的脉冲响应辨识，与实际模型的脉冲响应相比较（注：三个excel表必须放在matlab/work文件夹下才能运行）(Second-order model to a model of impulse response identification, and achieved through building simulink model for two groups of input- output data, a Gaussian noise in the interference with access to u1-y3, another group in the absence of Gaussian noise of access to the u1-y1, these two sets of data haar Wavelet-based impulse response identification, and the actual model of the impulse response comparison (Note: Three excel table must be on the matlab/work folder to run ))

Dark_Channel图像去雾，分割部分采用的是guide_filter而源文献中的Soft_Matting，运算效率有较大提升。输入文件地址及文件名需要自己修改。(Dark_Channel Haze Removal, using guide_filter other than soft_matting.)

几个利用uicontrol进行gui编程的matlab脚本文件：生成菜单修改fig颜色，绘制正弦并允许字体调整，归一化二阶系统的阶跃响应(use gui programming for the Matlab script file : Generation fig menu changes color rendering fonts sinusoidal and allow adjustments to a second-order system of the step response)

spectral subtraction

QAM is quadrature amplitue modulation...in wireless communication...this code is used to control the exceeding power of some mobile users..

异步电动机数量控制完整仿真模型，可以根据实际情况写该参数，达到研究者所需要的情形(The number of complete induction motor control simulation model, the parameter can be written according to the actual situation, the researchers needed to achieve the situation)

说明：  实现MMC的三相闭环控制和尖锐脉冲去除源代码(Realization of three-phase closed-loop control of MMC and source code removal of sharp pulse)
