It is really a good book,share with all of you. )

四元数双曲空间的一些计算函数，主要包括求四元数的逆，相乘运算等(Some function for the quaternionic hyperbolic space, including the inverse and the product ect.)

重型汽车车内声压级预测与主要噪声源分析 中国重型汽车正成为中国汽车产业在国际市场上最具竞争力的强势产业，但 目前国产重型汽车的 NVH（Noise,Vibration and Harshness）性能和国际先进水平 之间仍存在一定的差距。 (Heavy automotive interior SPL prediction and analysis of the major sources of noise China National Heavy Duty Truck is becoming China s auto industry the most competitive in the international market a strong industry, but At present, the domestic heavy-duty vehicles of NVH (Noise, Vibration and Harshness) performance and the international advanced level There is still a gap between.)

matlab GUI 的一个课程设计报告。里面介绍了编写GUI图像处理界面的方法与步骤，还配备了源程序。(matlab GUI of a curriculum design report. Which describes the preparation of image processing GUI interface methods and procedures, but also equipped with a source.)

ARMA模型基于时间序列分析和预测，ARMA matlab程序源代码(ARMA model based on time series analysis and forecasting, ARMA program matlab source code)

对简单闭环系统的PID控制参数进行优化，得到最佳的控制效果。使用时将该文件夹设为matlab默认文件夹，用simulink打开.mdl文件，在命令行窗口输入.txt文档中命令，可以得到优化后的P、I和D参数。(The PID control parameters of the simple closed-loop system are optimized to obtain the best control effect. With using these codes, the folder must be set as the default folder of matlab, then open the. MDL file, and input the commands of . TXT document in the command line window. The optimized P, I and D parameters will be obtained.)

说明：  采用多相滤波结构，可利用多个阶数较低的滤波来实现原本阶数较高的滤波，而且每个分支滤波器处理的数据速率仅为原数据速率的I/D，这为工程上高速率实时信号处理提供了实现途径。(By using polyphase filter structure, the original higher order filtering can be achieved by using multiple lower order filters, and the data rate processed by each branch filter is only I/D of the original data rate, which provides a way to realize high-speed real-time signal processing in engineering.)
