The evolution the speed of wind according to time is modelized by a function analytical or generated by a statistical law starting the data of measurement for a given site. In a context of theoretical modeling, the profile of wind must satisfy two criteria: 1) The duration of the profile must be limited to reduce the time of simulation 2) The profile of the wind must be representative of the characteristics of the deposit (intensity, variability, statistical distribution…). In this study, we represented the evolution the speed of the wind, by a scalar function which evolves/moves in time, modelized in deterministic form by a sum of several harmonics. Profile of the wind simulated with a mean velocity of 8.2m/s.

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.)
