| Title: | Validated solutions of saddle point linear systems | Authors: | Kimura, T Chen, X |
Issue Date: | 2009 | Source: | SIAM journal on matrix analysis and applications, 2009, v. 30, no. 4, p. 1697–1708 | Abstract: | We propose a fast verification method for saddle point linear systems where the (1,1) block is singular. The proposed verification method is based on an algebraic analysis of a block diagonal preconditioner and rounding mode controlled computations. Numerical comparison of several verification methods with various block diagonal preconditioners is given. | Keywords: | Saddle point matrix Numerical verification Block preconditioning |
