摘要
给出了行扩展正行列式的定义,证明了三个计算方法数的定理,从而将用正行列式解决排列问题的方法推广到含附加条件的n类元素的排列问题.
Getting the definition of positive determinant, and proving three theorems of calculating the number of methods, generalize the way of solving permutation problem with positive determinant to permutation problem of indefinite elements with additional condition.
