代码中几乎每一行都有自己的注释，参看算法的思想和步骤再来看应该不难
相应的测试函数以及测试数据集也一并上传（Iris，Balance-scale，Glass），程序中写的是绝对路径，需要自己改下(Almost every line of the code has its own comments, see the idea and steps of the algorithm look should not be difficult
The corresponding test function and the test data set also upload (Iris, Balance-scale, Glass), the program is written in the absolute path, need to change their own)
