homework 3-1 is difficult

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.)

MAP的MATLAB代码及其turbo卷积码应用程序代码(MAP and turbo convolutional code applications)

in this package are the programs needed to solve any eigenvalue problem.

DCT变换：变换域系数选取采用阈值编码，：阈值越小，图像恢复效果越好，但压缩效果差，一般取在5-10 即可很好的获得恢复图像信息。(DCT transform: transform domain coefficients selected using the threshold coding: the smaller the threshold value, the better the image restoration, but the compression is poor, and generally in the 5-10 to get a good recovery image information.)
