摘要
指出了“矩阵经过行初等主换而得到的行标准形是惟一的”这个结论的证明并不是很容易的.应用矩阵的行标准形是惟一的性质。讨论了与线性方程组的同解性有关的一些问题.
It is is not an easy thing to prove the conclusion that a matrix has a unique row-canonical form by a finite sequence of elementary row operations, then using this conclusion we discuss several problems of the systems of linear equations concerned in the property of same solutions.
