摘要: 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.数值算例表明该算法是有效的.Abstract: 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.
