IIR数字滤波器的设计 上学的时候一直不知道如何用C语言来编写IIR滤波器，终于找到了，上传给大家 希望能帮到大家。(IIR digital filter design when the school did not know how to use C language to write IIR filters, and finally found it, upload to hope to help you.)

说明：  s=21的s-随机交织图样代码 matlab下生成1024位图样，直接运行(s = 21 for s-random interleaver design code)

里面是一些大家很可能常用到的聚类分析方法有像K均值等分析法，希望能为大家提供一些帮助。(There is probably some people used to the cluster analysis methods such as K-means analysis, We hope to provide some help.)

"introduction to the finite element method in electromagnetics"是一本特别好的FEM的入门书籍，源码已上载。 这本书才115页，但是把FEM讲的很细，读完之后再读金建明的书就特别容易了。(introduction to the finite element method in electromagnetics is a particularly good introductory FEM books, source code has been uploaded. This book is only 115, but the FEM stresses very small payment to read after reading the book Jianming particularly easy.)

matlab 编程的函数库，便宜编程时查找(matlab programming library, look for cheaper programming)

调用noissin.dat的数据，对其做一维DCT及逆DCT，研究对DCT的结果舍去不同点数后的重建情况(Call noissin.dat data, do their one-dimensional DCT and inverse DCT, the results of research on the DCT rounding after the reconstruction of different points)
