Let H be the real quaternion field,C and R be the complex and real field respectively.Clearly R(?)C(?)H. Let H<sup>m×n</sup> denote the set of all m×n mat
Nonlinear Galerkin methods are new schemes for integrating dissipative systems:In the present paper, we obtain the estimates to the rate of convergence of such
We study how to use the SR1 update to realize minimization methods for problems where the storage is critical. We give an update formula which generates matrice
We structure a kind of rational splines far introducing some of the Pade approximent techniques into rational splines.In this paper,the results on the existence
Bordered linear systems arise from many industrial applications, such as reservoir simulation and structural engineering. Traditional ILU preconditioners which
Let K<sup>n×n</sup> be the set of all n×n matrices and K<sub>r</sub><sup>n×n</sup> the set {A∈K<sup>n×n</sup>|rankA=r} on askew field K. Zh
