二维波导中计算反射系数，两边为PML，上下为PEC，波源为平面波(two-dimensional waveguide reflection coefficient calculated on both sides of the PML and bottom of the PEC, for the plane wave Boyuan)

针对“BreastCancer”数据集，作为对比，第一次对特征集直接进行SVM分类，第二次使用粒子群算法进行特征选择后再进行SVM分类。并且对比和分析了两次分类的结果。(For "BreastCancer" data set, as a comparison, the first time the feature set is directly classified by SVM, and the second time the feature set is selected by particle swarm optimization before SVM classification. The results of the two classifications are compared and analyzed.)
