在matlab中利用odesolver进行单自由度有阻尼体系的时程分析，该代码使用时读入地震响应加速度（可为真实数据也可修改为理想函数），所有结构参数可调。输出加速度、速度和位移时程图像。(In the matlab in the use of odesolver single degree of freedom damping system of time history analysis, the code used to read the earthquake response acceleration (for real data can also be modified to the ideal function), all structural parameters adjustable. Output acceleration, speed and displacement time image.)
