摘要 利用细分和迭代的思想,细分了矩阵的指标集,构造了迭代系数,给出了广义Nekrasov矩阵的一组细分迭代判定条件,并用数值算例说明了判定条件的有效性. In this paper,based on the subdividing and iterative idea, by subdividing the index set of a matrix, and constructing iterative coefficients, a set of subdividing and iterative criteria of generalized nekrasov matrices are given. Effectiveness of the criteria is illustrated by a numerical example.
