多自由度比例阻尼系统matlab模态分析，包括各种输出频响图形。-Matlab multiple degrees of freedom damped system modal analysis, including the output frequency response graph.

用MATLAB里的simulink功能，采取独立模态控制方法，比较有控制和无控制的位移情况。(Using the Simulink function in MATLAB, the independent modal control method is adopted to compare the displacement with control and without control.)
