SIAM JOURNAL ON SCIENTIFIC COMPUTING 1996年 第1期17卷 260-262页
作者: Li, L Hu, J Nakamura, T TOHOKU UNIV GRAD SCH INFORMAT SCISENDAIMIYAGI 980JAPAN
In this paper, we show a simple parallel algorithm for polynomial evaluation. By this method, we only need 2N/p + log(2) p steps on p processors (where p less than or equal to O(N-1/2)) to evaluate a polynomial of deg... 详细信息

NUMERICAL LINEAR ALGEBRA WITH APPLICATIONS 1998年 第2期5卷 123-139页
作者: Gustafsson, I Lindskog, G Chalmers Univ Technol Dept Math S-41296 Gothenburg Sweden
The discretized linear elasticity problem is solved by the preconditioned conjugate gradient (pcg) method. Mainly we consider the linear isotropic case but we also comment on the more general linear orthotropic proble... 详细信息
