可以求出复杂网络中两节点间的距离以及平均路径长度，各节点的度及度的分布曲线，以及节点的聚类系数。(You can find out the distance and average path length between the two nodes in complex networks .you can also find out degree and degree distribution curve of each node, and the node clustering coefficient.)

对一个全彩色图像进行色彩通道的分解，从而可以看到不同的颜色通道下的图像。(IMCOLORSEP Displays the RGB decomposition of a full-color image)

温纳滤波，运用在影像上面的工具，简单的作业程式。(Wenner filter, using the tools in the image above, a simple job application.)

This code uses MATLAB s Internal Functions and Memory Preallocations to apply a Fast Implementation of kmeans algorithm. This is a efficient code for clustering a gray or Color image or it can be used for clustering a Multidimensional Array. Comparison. 1. Faster than MATLAB s internal kmeans function. 2. Consistant Output than internal kmeans. 3. 100 convergence.
