matlab MIMO仿真工具箱，含使用说明(Matlab simulation toolkit for use with)

基本模拟调制及其功率谱密度函数，有图的仿真结果，可以比较直观的进行理解(The basic analog modulation and power spectrum density function, a simulation results, can be more intuitive to understand)

mfcc 的matlab的实现，此方法在matlab上运行成功(mfcc the matlab realization this method successfully run in matlab)

利用该代码可以轻松实现模糊聚类分析 具体运用只需要直接在主程序上赋给分析的数据矩阵 便可以得到聚类图以及相关分析结果 也许不是很完美 实际应用可以小作调整(The matlab code is useful in fuzzy mathematics.)

很好的小波应用实例文档，介总结内容有小波用于去噪、图像压缩、边界扭曲、图像融合、小波包的分解和重构等等，附详细的MAMTLAB代码(Application of wavelet good document, refer to summarize the contents of wavelet denoising, image compression, border distortions, image fusion, wavelet packet decomposition and reconstruction, etc., with detailed MAMTLAB code)

稀疏分量分解。 function [y A]=sparseBSS1(X,L,langda,G,h,delta)(function [y A]=sparseBSS1(X,L,langda,G,h,delta) ---------------------------------------------------------------- 2009-04-15 YangZhicong X: observed signal,each row correspond to a sensor observations L: the length of FFT (or the length of Hanning window) langda: adjust the desired angular width G: discretize the potential field by taking a sample of G points h: threshold y: estimated sourses A: estimated mix matrix )

K均值（用matlab实现花的分类，附注释，程序简单）(K-means (machine learning job classification flowers))

在科研中，大量时间花在统计年鉴的搜集上，例如找《中国城市统计年鉴》中2000多个市，要对分散的八个城市群找对应的数据，如果每次筛选会花费大量时间，如果做好excel表头，把对应的城市写上去会在多个文件多个工作组查找满足要求的数据，直接按需要保存成excel，进行后续分析。(In the research, the amount of time spent on the Statistical Yearbook of the collection, for example, to find " China City Statistical Yearbook" in more than 2000 cities and want to find a group of eight cities scattered corresponding data, if each screening will spend a lot of time, If you do excel header, the corresponding write up the city will look to meet the requirements of data in multiple files multiple workgroups, saved directly as needed to excel, for subsequent analysis.)
