频率响应分析 系统Nyquist曲线的绘制；系统Bode图的绘制-Frequency response analysis ；Nyquist curve drawing system；系统Bode图的绘制

很好的编程matlab例子，控制过程对象的频率分析。伯德图的描述能够很好的帮我们分析系统的动态和稳态特性-Good programming matlab example, the control process object frequency analysis. Descr iption Bode diagram can help a good dynamic and static characteristics of our analysis system

边界测试是用来探测和验证代码在处理极端的或偏门的情况时会发生什么。-Boundary testing is used to detect and verify the code what happens when dealing with extreme situations or vice.
