地震响应Matlab代码 odesolver
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.)

说明: matlab实验 用给定的多项式,y=x3-6x2+5x-3,产生一组数据(xi,yi,i=1,2,…,n),再在yi上添加随机干扰(可用rand产生(0,1)均匀分布随机数,或用rands产生N(0,1)分布随机数),然后用xi和添加了随机干扰的yi作的3次多项式拟合,与原系数比较。
如果作2或4次多项式拟合,结果如何?
(matlab experiment with a given polynomial, y = x3-6x2+5 x-3, generated a set of data (xi, yi, i = 1,2, ..., n), then add random noise in yi (available rand generation (0,1) uniformly distributed random number, or rands generated N (0,1) random numbers), then xi and yi to add a random disturbance polynomial fitting for the three times, compared with the original coefficient . If 2 or 4 times for polynomial fitting, the result?)
