判定H-矩阵的一个迭代算法的修正(英文)

The modified algorithm of iterative criterion for H-matrix

随着H -矩阵在科学与工程计算中的广泛应用 ,如何判定一个给定矩阵是否为H -矩阵引起了许多研究者的兴趣 .本文对一个现有判定H -矩阵的迭代算法进行了修正 ,得到了一个新的迭代算法 .

For wide applications of H-matrix in engineering and scientific computing, it arouses many researchers interesting how to identify whether a given matrix is an H-matrix or not. A new iterative criterion algorithm for distinguishing H-matrices is proposed. Numerical examples show that the algorithm is effective.
