摘要
定义了k阶排列矩阵和(r+d)阶r-排列矩阵的概念,利用k阶排列矩阵和r-排列矩阵研究了d—析取矩阵、(d,e)-析取矩阵、(d,r,z]-析取矩阵的构造及其行数的行界.
Notions of k order permutation matrix and(r+d)order r-permutation matrix were defined.The d-disjunct matrix and(d,e)-disjunct matrix and(d,r,z]-disjunct matrix and their row bounds were studied by the k order permutation matrix and the(r+d)order r—permutation.
