摘要
给出了判定非广义对角占优矩阵的充要条件,从理论上彻底解决了不可约非广义对角占优矩阵的判定问题,并给出了判定不可约非广义对角占优矩阵的具体算法.
A necessary and sufficient condition for judging nongeneralized diagonally dominant matrices is given,theoretically,it thoroughly solves the problem of judging irreducible nongeneralized diagonally dominant matrices,a concrete algorithm for judging irreducible nongeneralized diagonally dominant matrices is given.
