是信号处理的基础，实现典型相关分析，利用matlab写成的窄带噪声发生。( Is the basis of the signal processing, Achieve canonical correlation analysis, Using matlab written narrowband noise occurs.)

实现Verilog编程，实现超声波测距模块实现测距功能，并将测得的距离显示在数码管上(Verilog programming is realized, ultrasonic ranging module is realized, and the measured distance is displayed on the digital tube)

双势井duffing方程分叉演示程序。演示Duffing方程在不同系数选择下单周期，准周期，混沌的产生。(Double potential wells duffing demo program bifurcation equation. Demo Duffing equation coefficients in different choices under the single-cycle, quasi-periodic, chaos generation.)

说明：  在MATLAB环境下，分别建立了5、7、9级MMC直流传输模型，验证了CPS-SPWM模式的特性。结果表明，对于低电平MMC变换器，PWM具有良好的逼近调制波的能力，谐波分量少，等效开关频率低。(In the MATLAB environment, MMC DC transmission models of 5, 7 and 9 levels are built respectively, and the characteristics of CPS-SPWM mode are verified. The results show that for low-level MMC converter, PWM has a good ability to approach the modulation wave, with less harmonic components and less equivalent switching frequency rate)

Android手势识别的实现附上源代码，在屏幕上方划动手指，即可实现手机的响应，执行相应的操作，比如滑动、切换屏幕、图片放大、打开应用程序等，自动判断手势相似度，比较基础的安卓手势操作例子。

从老外文章里看到一种基于分类器的人脸检测方法，好不容易搞到这个人脸图像训练集和测试集，现在贡献出来，希望对做人脸检测的朋友有帮助（图像比较全，有彩色人脸图像）-from generals saw an article based on the classification of face detection method finally got the facial image training set and test set, now contribute, hope to the human face detection and friends to help (the whole picture, color facial image)

说明：  股票价格预测，支持向量机回归预测，核函数，(svm for stock price forcast)

说明：  逆变器的simulink仿真，采用dq解耦的空间矢量控制模式(Inverter simulink simulation, using dq space vector control mode decoupling)
