通过MATLAB对一幅多个人物的图像进行，人脸轮廓的提取，识别。效果不错，譬如毕业照这样的照片能有很好的结果。(By MATLAB to more than one person in the image , extract facial contour recognition . Good results, such as this photo graduation photo can have a good result .)

VB程序中实现调用MATLAB的方法. 介绍了在VB 应用程序中利用动态数据交换和ActiveX自动化(OLE自动化)协议实现的两种调用MATLAB函数的方法。通过这两种方法实现了VB的可视化界面与MATLAB 强大的数值分析和图形显示的能力的结合。(Introduced in VB application using Dynamic Data Exchange and ActiveX Automation (OLE Automation) protocol calls MATLAB function of the two methods. Achieved by either method, the visual interface of VB and MATLAB powerful numerical analysis and graphical display of the ability of combination.)

matlab函数查询手册，很实用的辅助工具(the matlab function query manual, very useful aids)

本压缩包里面有几个月的光伏数据，文件里有几个当时计算用的几个小程序，求光伏概率分布的，(The compressed inside a few months photovoltaic data, there are several file was calculated using a few small programs, find the probability distribution of PV,)
