用分块迭代法求解稀疏最小二乘问题 %A 蔡大用 %J 计算数学 %D 1985 %I %X In this paper, we consider the block-SOR and SSOR iterative methods for solvinga least-squares problem with a large sparse coefficient matrix. The result about the convergence of the block-SOR iteration is given in 1]. TheSame result is derived here by means of a more straightforward method. We show that the block-SSOR iteration is "absolutely" convergent in a sense. %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=6E709DC38FA1D09A4B578DD0906875B5B44D4D294832BB8E&cid=37F46C35E03B4B86&jid=CC77F3CEF526D9CF0B3021650FB4E57E&aid=014913690686787520D1B9A4D76B4048&yid=74E41645C164CD61&vid=DF92D298D3FF1E6E&iid=38B194292C032A66&sid=AF507FDD66D991DA&eid=DFEE4E8C33C95CEF&journal_id=0254-7791&journal_name=计算数学&referenced_num=1&reference_num=0
