矩阵方程AX=0,AX=B有解的充要条件的一个简单证明

Matrix equation AX =0, AX = BHas the solution sufficiently to want the condition a simple proof

矩阵方程AX=0,AX=B有解的充要条件通常用方程组理论进行证明,本文用矩阵或向量组的理论,给出一个简单的证明方法.

Matrix equation AX = 0, AX = B Some solutions sufficiently want the condition to pass the commonly used system of equations theory to carry on the proof, This article uses the matrix or the vector group＇s theory, Produces a simple proof method.
