一组取值为+/-1的随机序列，每两个数据之间插入3个0，然后将序列通过一个设计好的根升余弦滤波器，并用周期图法和Welch法分别绘制信号的功率谱。再次通过根升余弦滤波器后用stem函数绘图。(A set of values ​ ​ is+ /-1 random sequence inserted between every two data 3 0, then the sequence through a root raised cosine filter designed, periodogram and Welch method to draw the signal powerspectrum. Stem function by root raised cosine filter with drawing again.)

ACA_TSP是用蚁群算法（ant colony algorithm）解决旅行商问题（travelling salesman problem）。文件打开后运行ACA_TSP.m文件即可得到结果，代码中有详细注释，方便修改。运行示例已经保存为图片附在压缩包中。(ACA_TSP is to solve the traveling salesman problem (travelling salesman problem) ACO (ant colony algorithm). Run ACA_TSP.m file to get the file to open the result, the code has detailed notes, easy to modify. Run the sample has been saved as a picture attached to the compressed package.)

天在维普下载了一篇SPIHT算法改进的论文，（耿兴云，《基于改进SPIHT的静态图像编码》，电脑知识与技术：学术交流-2007年5期），我根据该文提出的改进算法，用Matlab来实现，却发现改进算法的程序运行速度比原算法还要慢，希望有兴趣的朋友进来看看，评论一下原因。(Days in the VIP downloaded a SPIHT algorithm to improve the paper, (Gengxing Yun, " based on improved SPIHT still image coding," Computer Knowledge and Technology: 5-year academic exchange-2 007), in accordance with this paper the improved algorithm Matlab to achieve, but found that the improved algorithm runs faster than the original algorithm is also slow, hope to have interested friends come to see, comment on why.)
