In this paper we consider the problem of solving a sequence of linear systems with coefficient matrix A α =I + αA (or A α =αI + A), where α is a real paramater and A is skew-symmetric matrix. We propose to solve this problem exploiting the structure of the Schur decomposition of the skew-symmetric matrix and computing the Singular Value Decomposition of a bidiagonal matrix of halved size.

Abstract
In this paper we consider the problem of solving a sequence of linear systems with coefficient matrix A α =I + αA (or A α =αI + A), where α is a real paramater and A is skew-symmetric matrix. We propose to solve this problem exploiting the structure of the Schur decomposition of the skew-symmetric matrix and computing the Singular Value Decomposition of a bidiagonal matrix of halved size.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
