You all might have used CTime or CTimeSpan to manipulate the system timer. Here is an article to show you how your system timer works. I will give you an idea of port communications behind the system clock manipulations. Those who are a little biased on hardware and software interfacing practices would find this article of great help.

matlab的，希望对大家有用,谢谢多交流 (matlab, and I hope useful for everyone, thank you more exchanges)

简单描述了在MATLAB中的一些常用的绘图语言，规则和技巧(Briefly describes some of the commonly used in the MATLAB graphics language, rules and techniques)

进行T-S模型的离线辨识程序，只需要有数据，直接代入就可以辨识出T-S模型的center以及后件参数，非常实用，并有误差曲线提供分析(offline T-S fuzzy model identification，a erorr map is provided for T-S model effectivity analysis.)

该程序实现改进的自适应相关算法，两个matlab文件，一个为函数，该函数求出信号特征量的马氏距离平方并通过梯度下降法训练出其固定阈值，另一个为主函数，调用该函数文件；该程序将4路信号，每一路信号特征量的马氏距离平方及其固定阈值求出来，并一起画出图来。 (The program features improved adaptive correlation algorithm, two matlab files, one for the function that calculate the square of the Mahalanobis distance of signal characteristics by gradient descent to train the fixed threshold, the other main function, call The function files the program seek out the square of the Mahalanobis distance and fixed threshold of each channel signal, there are four chanel signal,then draw them out together)
