计算方法数值方程，用列主元Gauss消去法解释线性方程组Ax=b，其中A=[10E-8 2 3,-1 3.712 4.623,-2 1.072 5.643],b=[1,2,3]
English Description：
The calculation method is numerical equation. The column principal element Gauss elimination method is used to explain the linear equation group AX = B, where a = [10e-8 23, -13.7124.623, - 21.0725.643], B = [1,2,3] < br / >
