BAMPHI: Matrix-free and transpose-free action of linear combinations of φ-functions from exponential integrators

The time integration of stiff systems of Ordinary Differential Equations (ODEs), usually arising from the spatial discretization of Partial Differential Equations (PDEs), constitutes a hot topic in numerical analysis. In particular, exponential-type integrators have attracted much attention for thei...
