【摘要】 以矩阵范数性质的块对角占优矩阵和广义严格对角占优矩阵为工具,利用矩阵分块的方法引入了矩阵非奇异的判定条件,讨论了矩阵非奇异性的判定准则,并利用数值例子说明了所给结论的可行性和有效性.更多还原

【Abstract】 This paper uses block diagonally dominant matrices and generalized strictly diagonally dominant matrix based on the nature of the matrix norm as tools,uses matrix partition method the nonsingular to import matrices conditions,discusses the criterias of the nonsingularity matrices,and uses the numerical examples to illustrate the feasibility and effectiveness of the conclusions.更多还原
