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.
