Skew-symmetric inner product, optimal symplectic Householder transformations, SR factorization, error analysis, backward and forward errors, implementation, factored form,

Note that in the nonsymmetric examples, the number of required ADI iterations j iter for the V - shifts is not always smaller than that of the heuristic shifts (see, e.g.,

Lanczos bidiagonalization is a competitive method for computing a partial singular value decompo- sition of a large sparse matrix, that is, when only a subset of the singular values

These results let us hope, and later confirm, that deferred correction schemes can be established using rational interpolants with equispaced nodes, polynomial reproduction

As standard algorithms for the solution of Sylvester equations are of limited use for large-scale (possibly dense) systems, we investigate approaches based on the iterative

In a vertical cell, cathode above anode, in the presence of growth, our model predicts that the fluid concentration near a downward-growing tip is lowered, thus generating a vortex

Those results are obtained for spatially variable diffusion coefficients and the Robin parameters optimized by assuming constant coefficients (gray dashed line) or the full

In particular, in the one-class model, we prove that a paper which receives a new citation has an increase of its rank which is larger than the increase received by the other
