Greedy Group Sparsity Promoting Optmization

复杂网络matlab样例（只要为sy003.m），包括求平均度，路径直径，平均路径长度，聚类系数，介数（需要加载bgl工具箱），核数，紧密度等(Complex network matlab sample (as long as it sy003.m), including the degree of averaging, the path diameter, the average path length, clustering coefficient, betweenness (bgl need to load the toolbox), auditing, tightness, etc.)

说明：  巴特沃思和契比雪夫滤波器，有wav文件以及输出的wav文件，使用带通滤波器，保留了300-3300Hz的音频，可以广泛使用在音频滤波方面(Butterworth and Chebyshev filter, wav files and output wav file, the use of band-pass filters, retained the 300-3300Hz audio can be widely used in audio filtering)

现代数字信号处理，本章主要介绍滤波器相关内容(advance digital signal processing)

matlab神经网络newff函数用来创建网络，为BP神经网络设置参数(newff is very important of BP.)

UNIX网络编程第2卷 进程间通信。学习Linux很好的书籍(UNIX Network Programming Volume 2 Interprocess communication. Good books to learn Linux)

彩色图转灰度图++matlab+实现代码，很不错，值得看看！(Color to grayscale++matlab+ implementation code, very good, worth a look!)

很好的matlab书籍！供大家学习参考。请同行批评指正！上传更好更高质量的文章。程序和源代码！(Matlab good books! Reference for them to learn. Peer criticism please! From the article, higher quality better. Procedures and source code!)

matlab 产生高斯随机粗糙面的函数 输入变量为点数 长度 相关长度 均方根高度(matlab generate Gaussian random rough surface function of input variables for the points the length of root mean square height correlation length)

经典信号处理程序可以为初学者提供一点点帮助吧 (Classical signal processing procedures can be provided for beginners a little bit of help you)
