The Computation of Elementary Unitary Matrices

Abstract

The construction of elementary unitary matrices that transform a complex vector to a multiple of e (sub 1) the first column of the identity matrix, are studied. We present four variants and their software implementation, including a discussion on the LAPACK subroutine CLARFG. Comparisons are also given.
