数字信号处理之时域卷积matlab实现，非常简单。(Digital signal processing implementation of time-domain convolution matlab)

说明：  这是一个用Matlab编写的提取图像轮廓并且标示出图像中拐点的例子，输出拐点的坐标。(This is an extract prepared using Matlab image contours and marked a corner in the example image, the output coordinates of corner.)

对图像做傅里叶频谱变换，可以求出图像的频谱分布，实现频谱中心化(Fourier transform spectrum of the image to do, you can find the spectral distribution of the image to achieve the center of the spectrum)

粒子群算法的MATLAB源码，代码运行平台为Tc 3.0 ，对研究粒子群算法问题的朋友较有参考意义。(Particle Swarm MATLAB source code for the operating platform Tc 3.0, the study of particle swarm optimization Friends of the problem than there is reference value.)

复杂网络中有一些常见的基本模型，如随机图，WS小世界网络，NW小世界网络及BA无标度网络等，本程序从这些网络的产生机理，生成了这些复杂网络模型，并且分析了其基本性质如平均路径长度，聚类系数及度分布等。(Complex networks have some common basic model, such as random graph, WS small-world networks, NW small-world networks and scale-free BA network, the program generated from the mechanism of these networks to generate the complex network model and analysis its basic nature, such as the average path length, clustering coefficient and degree distribution.)

卷积码的编解码，译码采用维特比译码。编码包括zero-biting和tailing-biting两种方式。(Decoding convolutional codes, Viterbi decoding used. Code, including zero-biting and tailing-biting two ways.)

说明：  这里有2组图，“1000.0.05”这一组是运行结果比较好的一组图，但是当时修改了时间间隔而没有改坐标说明，所以db1000.0.05.fig这幅图的坐标说明后来做了人工改正（应该是“time(0～250ms分成5000组,步长0.05ms”）。(Reuters, "1000.0.05" This group is running a relatively good results Reuters. But then amended the time interval and not changed coordinates Note So db1000.0.05.fig site map coordinates statement later became the artificial correction (should be "ti me (0 ~ 250ms group into 5000, 0.05 Step ").)
