中文说明：使用matlab对基于最小错误率的Bayes分类器进行仿真，编写了相应的程序，分为协方差相等和不相等两种情况，最后画出了三类的分界线
English Description：
Matlab is used to simulate the Bayes classifier based on the minimum error rate, and the corresponding program is compiled, which is divided into two cases: equal covariance and unequal covariance. Finally, the dividing line of three types is drawn
