Direction splitting of $φ$ -functions in exponential integrators for $d$ -dimensional problems in Kronecker form

Marco Caliari, Fabio Cassini

In this manuscript, we propose an efficient, practical and easy-to-implement way to approximate actions of $φ$ -functions for matrices with $d$ -dimensional Kronecker sum structure i…

A $μ$ -mode BLAS approach for multidimensional tensor-structured problems

Marco Caliari, Fabio Cassini, Franco Zivcovich

In this manuscript, we present a common tensor framework which can be used to generalize one-dimensional numerical tasks to arbitrary dimension $d$ by means of tensor product formu…
