提出了一类不一定对称的m -矩阵的正则分裂。如果矩阵是对称的，将这种分裂与共轭梯度法相结合，提供了一种快速迭代求解算法。与其他众所周知的方法进行了比较。在所有的测试问题中，新的组合比其他方法要快。
A particular class of regular splittings of not necessarily symmetric M-matrices is proposed. If the matrix is symmetric, this splitting is combined with the conjugate-gradient method to provide a fast iterative solution algorithm. Comparisons have been made with other well-known methods. In all test problems the new combination was faster than the other methods.
