bode图，可以实现如何绘制bode图的过程和详细步骤。-Bode figure, can realize how to draw the process and detailed bode figure steps

用MATLAB绘制系统Bode图和Nyquist图的方法，并通过系统的Bode图和Nyquist图分析系统的动态性能、稳定性和相对稳定性。-Method MATLAB mapping system Bode diagram and Nyquist plot, and through the dynamic performance of the system Bode diagram and Nyquist diagram analysis, stability and relative stab

通过对串口数据接收所得数据文件进行处理，进行FFT变换，绘制伯德图，并实现数据到正弦波形显示。(The data files received by the serial port are processed, the FFT transform is carried out, the Bode diagram is drawn, and the data is displayed to the sinusoidal waveform.)

用m文件绘画伯德图，利用hold on命令可以绘画多个伯德图，然后进行频率响应对比。(plot Bode diagram by m file)
