Exploiting the the nonzero diagonal pattern in matrix function computations
Majed Hamadi, Nezam Mahdavi-Amiri, Marcel Schweitzer
We consider the task of approximating a matrix function , where is a matrix in which only a relatively small number of (not necessarily consecutive) sub- and superdiagona…
