“…In practice, one can use some approximate methods, such as Krylov subspace methods for Sylvester equations (Hu and Reichel 1992;Li 2000), to solve the involved large-scale matrix equations at far lower cost. Further, noting thatP ,Q ∈ R n×r are high dimensional but thin matrices, the specific method proposed in Bouhamidi and Jbilou (2008) and Hodel and Misra (1997) fits into this situation and works efficiently. • In step (2), the projection matrices are defined directly via the matricesP jj andQ jj .…”

“…see, e.g., [6,9,20,22,31,33]. In the Extended Krylov subspace context, we can generate the matrices V m , T m by means of Algorithm 1, and then, following the Galerkin requirements, project the problem onto the space and require that the residual be orthogonal to it.…”

“…GMRES 算法还可用于求解诸如最优控制、滤波估计、去耦、降阶等控制理论中的微分 Riccati 方程 [27] 。在 大特征值问题和边值问题中会出现多元线性系统, 线性控制、 滤波理论、 图像修复等方面包含了著名的 Lyapunov 矩阵方程、Sylvester 矩阵方程和 Stein 矩阵方程,这些方程同样是典型的多元线性系统问题,全局 GMRES 算法 正好为这些问题的解决提供了一个很好的工具,不同的数值实验更显示出该方法收敛行为方面的优势 [28,29] 。 GMRES 算法还用于求解 Toeplitz 方程、Helmholtz 方程和 Navier-Stokes 方程等,预处理 GMRES 并行算法也得 到了很好的应用 [30][31][32][33] 。在太阳物理的研究中,我国科学家颜毅华于 1995 年首次推导出太阳常 alpha 无力场的边 界积分表示, 并用边界元方法实现了数值求解 [34] ; Li 等人 2007 年对颜毅华的算法进行了改进, 他们引入 GMRES 算法来解决边界元方程组;由此,对 10,000 阶以上的矩阵,用 GMRES 算法使得计算效率提高了 1000~9000 倍 [35][20] 实型 Laplace 变换的线性方程组 光谱延迟修正技术 [21] 微分代数方程的初始值问题 控制、光辐射和流体力学 [23][24][25][26] 近海水域控制方程、光学辐射传输方程、计算流体力学 Euler 方程 控制理论 [27] 微分 Riccati 方程 大型奇异值问题 [28] 广义希尔维斯特矩阵方程 太阳物理研究 …”
