利用降阶定理计算行列式中的最小阶数

Calculation of the minimum order of determinant by using descend order theorem

通过讨论利用降阶定理计算行列式中的最小阶数问题,给出了分解的最小阶数,同时结合矩阵的满秩分解,给出了一种有效的行列式的计算方法。

In this paper, the minimum order is determined by using descended order theorem. Meanwhile, through decomposition of matrix, we obtain an effective approach to calculate the determinant.
