m×n矩阵的伴随矩阵的概念、性质及应用

The Adjoint of an m×n Matrix and Its Propertiesand Applications

把方阵的伴随矩阵及三个基本性质推广到一般的m×n矩阵,由此给出一类线性方程组的简明的求解公式。

This paper generalizes the concept of the adjoint of a square matrix and its three basic properties to the case of an ordinary mX n ma trix. Then a simple formula follows to solve a system of linear equations
