In this paper we study the decay behaviour for the entries of functions of skew symmetric matrices arising in the applications.

Abstract
In this paper we study the decay behaviour for the entries of functions of skew symmetric matrices arising in the applications. Thanks to an algorithm proposed in [4] for computing the exponential of tridiagonal skew symmet- ric matrices we will be able to study the decay behaviour of more general functions of matrices and to define a banded version of such function of matrices. Numerical tests show- ing this kind of behaviour are reported for several kind of functions.File in questo prodotto:
