matlab灰色预测模型问题，并求出相对误差(The problem of the matlab gray prediction model, and calculated the relative error)

该程序的优点在于障碍可以自己设置，也可以读图。(The advantage of this program is that obstacles can be set by themselves or read pictures.)

coding for generating a mel filter bank for a given frequency vector

说明：  duda模式分类第二版的分类器工具箱，源代码(duda pattern classification the second edition of the classifier toolbox, source code)

This is a matlab code of LEACH protocol that simulates the life of the sensor network.

通过 MIMOsimSpectralHelp() 输入不同参数，可以模拟和比较在不同结构和环境下MIMO系统的性能；有助于我们理解MIMO。(Enter through MIMOsimSpectralHelp () with different parameters, you can simulate and compare the performance of different structures and environments in MIMO systems help us understand MIMO.)

将声音文件在时间轴上分割成几段，分别将段的秩序及某些段内的秩序颠倒，从而实现了对声音文件的加密。首先，先读取一个声音信号，对信号做1024点FFT变换，取完点之后，分成四个向量，四个向量组成一个矩阵，再对每一个向量进行转置，再重新整合，从而就实现了回密的过程。(Sound files on the timeline will be divided into paragraphs, each paragraph of the order and reversed the order of some paragraphs to realize the encryption of sound files. First, the first reading of a voice signal, the signal was 1024 points FFT transform, check after the completion point, divided into four vectors, the four vectors form a matrix, then for each vector transpose, re-integration, which will achieve a return to close the process.)

matlab 视频读取方式的研究，有好多种方法，很好用哟(matlab video read mode, there are a variety of methods well with yo)

this is a matlab function that can be given to the genetic algorithm tool box to chose the best 10 positions of 1 s beside the original 6 in the upper left corner 1 s in the dct quantization matrix

关于复杂网络的聚类系数算法，用matlab计算，矩阵为稀疏矩阵。(clustering_coefficients(A) returns the clustering coefficients for all vertices in A. The clustering coefficient is the ratio of the number of edges between a vertex s neighbors to the total possible number of edges between the vertex s neighbors. )
