matlab连接数据库SQL，然后打开数据库表格，并读取表格中的数据，进而对数据库进行操作(matlab connect to the SQL, and then open the table, and read the data in the table, then the operations)

说明：  通过粒子群优化算法优化PID参数，该算法对pid控制器参数进行整定，pso能够对参数实现优化，且有良好的收敛性。(PSO algorithm tuning PID parameters)

说明：  微多普勒仿真，用于微多普勒仿真计算，方便快捷(Micro doppler simulation)

说明：  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.)
