对矩阵乘积的行列式性质|AX|=|A‖X|作进一步的推广,得到了更为普遍的结果;将其应用到微分方程以及其它相关的问题中,能够简化证明过程,并得到更进一步的结论.
In this paper, we popularize the equality of the determinant for matrix multiplication and get more common results; Applying the results to the differential equations and the other relative problems, we can simplify the proof as well as getting further conclusion.
