Based on the block style spectral decomposition,this paper deals with the optimal backward perturbation analysis for the linear system with block cyclic coeffic
A generalized Gauss-type quadrature formula is introduced, which assists in selectionof collocation points in pseudospectral method for differential equations w
In this paper we study L-shaped convex programming. An algorithm for it is given. The result of computation shows that the algorithm is effective. The algorithm
