应用多元高斯声束叠加方法建立粉末合金构件的声场模型(sound field simulation sound field simulation sound field simulation )

基于adaboost的人脸检测算法的matlab实现过程，希望对需要的朋友有帮助(Face detection based on adaboost algorithm matlab process, hope to help to friends)

说明：  该代码实现了频谱感知中的能量检测方法，对于能量检测的认识能有更深入的了解(The code implements the energy spectrum sensing in detection methods, knowledge of the energy detection can have a better understanding of)

Shunt Generator equation

是和网上的朋友共同一起研究，编写的，其中出现过好多的意见不一致， 并参考了大量的书籍和相关的资料。 经过多次调试(is online friends together, the preparation of which there a lot of disagreement, and a large number of reference books and relevant information. After repeated testing)

本程序是计算深海远场情况下的声源定位，首先要编译海洋环境文件（包含阵元信息），利用Krakren程序计算本征函数和本征模态，再利用本程序的子程序计算拷贝向量，然后合成声源信号，最后根据匹配场的程序进行匹配定位，由于数据量比较大，计算区域如果选的比较大的话，计算时间就比较长，酌情选择。(This procedure is to calculate the far-field sound source localization in case of deep sea, we must first compile the marine environment file (containing the array element information), use Krakren program to calculate the intrinsic function and the intrinsic mode, and then use a subroutine to copy the program to calculate the vector then synthesized excitation signal, the final match to locate the matching field program, because a large amount of data to calculate the area if the election is relatively large, the calculation time is relatively long, discretionary selection.)

系统深入得多，一些在第一本中只略微论及的高级内容，这里讲得完整透彻。理论与实践并重，可操作性强。例题都有可直接运行的matlab文件，正文中也给出了关键部份方便阅读。读完这本书，住真水平可以上一个台阶，基本上可以达到系统级仿真的能力。(System is much more depth, some in the first book deals with only a slight premium content here put a complete and thorough. Theoretical and a practical, easy to operate. Example are directly run matlab file, the text also gives a key part of user-friendly. After reading this book, the level of living can be really a new level, but basically can achieve system-level simulation capabilities.)

vmd源程序的修改版，看起来没那么费尽，更容易懂。(vmd source of the modified version, does not look so racked and easier to understand.)

可以进行经验模式分解的matlabd源程序(Empirical mode decomposition can be the source matlabd)

newmark法 进行时程分析 可能有个别小错误，欢迎指正...谢谢(newmark)
