Fortschritte der initialen Verätzungstherapie : zwei Augenspüllösungen im Vergleich

We have implemented a numerical code (ReLPM, Real Leja Points Method) for polynomial interpolation of the matrix exponential propagators exp (Delta tA) v and phi(Delta tA) v, phi(z) = (exp (z) - 1)/z. The ReLPM code is tested and compared with Krylov-based routines, on large scale sparse matrices arising from the spatial discretization of 2D and 3D advection-diffusion equations
