输入的影像可以是一个复杂的形象contaning点，纹理，缺陷等图形用户界面可以让用户手动识别中心，动态更新和纪念中心。标志着该中心可以在整个图像或它的一部分。一旦所有这些中心鉴定，RDF是由程序计算和策划，并包含一个txt文件保存中心的名单。(The input image can be a complicated image contaning dots, textures, defects etc. The GUI lets the user manually identify the centers, dynamically updating, and marking the centers. The centers can be marked in the whole image or a part of it. Once all the centers are identified, the RDF is calculated and plotted by the program, and a txt file containing the list of centers is saved. )

mfcc用于求取训练样本的特征值，其需要melbankm和enframe两个程序。 enframe用于将语音分帧，melbankm用于产生mel三角滤波器组，vqlbg用于获取说话人码书，disteu程序用于计算两个矩阵间的距离，(mfcc strike eigenvalues ​ ​ for the training sample, which requires melbankm and enframe two procedures. enframe for the voice of the frame, melbankm used to produce the triangular mel filter bank, vqlbg codebook is used to get people talking, disteu procedures used to calculate the distance between two matrices,)

matlab实现地震实现反射系数，激发出地震正演模拟中使用的各种频率的雷克子波(Matlab realize the reflection coefficient of earthquake, inspire Ricker wavelet seismic forward various frequency is used in the simulation )

说明：  二值图像区域生长，可以计算二值图像的区域增长的范围。(Binary image region growing, can calculate the binary image of the regional growth range.)

太阳黑子是人类长久以来感兴趣的问题。此处运用matlab代码对太阳黑子的记录的数据进行处理，希望能提供帮助( Using archival records,astronomers have applied Wolfer s rule to determine sunspot activity back to the year 1700. Today the sunspot index is measured by many astronomers and the worldwide distribution of the data is coordinated by the Solar Influences Data Center at the Royal Observatory of Belgium. The text file sunspot.dat in the matlab/demos directory has two columns of numbers. The first column is the years from 1700 to 1987 and the second column is the average Wolfer sunspot number for each year.)
