说明：  在模式识别应用中，用分支定界法(branch-and-board method)进行特征的选择。该程序在matlab环境下实现了该算法，以从六个特征中选择两个最佳特征为例(In pattern recognition applications, using branch and bound method (branch-and-board method) to carry out the characteristics of choice. The program in the matlab environment to achieve the algorithm to select from the following six characteristics of the best features of the two as an example)
