根据潜在震源区数据，利用matlab画第五代潜在震源区图，并在鼠标点击位置编号(According to the potential source area data, using matlab draw fifth-generation potential source area map and click on the mouse position number)

说明：  （1）应用9×9的窗口对上述图象进行随机抽样，共抽样200块子图象； （2）将所有子图象按列相接变成一个81维的行向量； （3）对所有200个行向量进行KL变换，求出其对应的协方差矩阵的特征向量和特征值，按降序排列特征值以及所对应的特征向量； （4）选择前40个最大特征值所对应的特征向量作为主元，将原图象块向这40个特征向量上投影，所获得的投影系数就是这个子块的特征向量。 （5）求出所有子块的特征向量。 ((1) the application of 9 × 9 window of these images at random, a total sample of 200 sub-image (2) all sub-images according to out-phase into a 81-dimensional row vector (3) all 200 lines for KL transform vector, derived its corresponding covariance matrix of eigenvectors and eigenvalues, in descending order by eigenvalue and the corresponding eigenvector (4) a choice to 40 corresponding to the largest eigenvalue eigenvector as the PCA, the original image block to the 40 feature vectors on the projection, the projection coefficients obtained by this sub-block eigenvector. (5) calculated for all sub-block eigenvector.)

用matlab软件实现蚁群算法，该算法适合组合优化问题的求解问题，应用该程序可以再软件上解蚁群优化问题(Matlab software using ant colony algorithm, the algorithm is suitable for solving combinatorial optimization problems issues, applications software, the program could be the issue on Ant Colony Optimization Solutions)
