本文采用最小平方误差准则(MSE准则)通过训练样本集建立线性判别函数，并用线性判别函数去判断测试集。 数据集报告： 1、男女生 2、sona 3、ups(In this paper, the least square error criterion (MSE criterion) the training sample set by a linear discriminant function, and a linear discriminant function to determine the test set. Data Set Report: 1, boys and girls 2, sona 3, ups)

将系数矩阵A转变成等价两个矩阵L和U的乘积 ，其中L和U分别是下三角和上三角矩阵。当A的所有顺序主子式都不为0时，矩阵A可以唯一的分解为A=LU。其中L是单位下三角矩阵，U是上三角矩阵。 (The coefficient matrix A into two matrices L and U is equivalent to the product, where L and U are lower triangular and upper triangular matrix. When A master style is not all the sequence is 0, the matrix A can only be decomposed into A = LU. Where L is unit lower triangular matrix, U is upper triangular matrix.)
