摘要
本文研究解大线性系统的对称的AOR(SAOR)方法。讨论了SAOR迭代的收敛性,进一步扩充了文[1]的结果,并在系数矩阵是对称正定矩阵的情况下,给出SAOR迭代谱半径的估计式。
For solving large linear systems, the method of symmetric accelerated overrela- xation (SAOR) is studied. The convergence of SAORiteration is discussed and the restilt of reference [2] is further extended. With a matrix of coefficients acts as symmetric positive definite matrix, an form la for esrirnating spectral radius of SAOR iteration is given.
