摘要
利用非零元素链理论和方法,研究了非奇异H-矩阵的判定问题,给出了几个新的判定条件,并用数值例子说明了所给判定条件的判定范围更加广泛.
The criteria were studied for nonsingular H-matrix. Some sufficient conditions for a matrix to be a nonsingular H-matrice are given by nonzero elements chain theory and methods, Advantages of results obtained are illustrated by a numerical example
