dlaed5.f(3) LAPACK dlaed5.f(3) NAME
dlaed5.f - SYNOPSIS
Functions/Subroutines subroutine dlaed5 (I, D, Z, DELTA, RHO, DLAM) DLAED5 Function/Subroutine Documentation subroutine dlaed5 (integerI, double precision, dimension( 2 )D, double precision, dimension( 2 )Z, double precision, dimension( 2 )DELTA, double precisionRHO, double precisionDLAM) DLAED5 Purpose: This subroutine computes the I-th eigenvalue of a symmetric rank-one modification of a 2-by-2 diagonal matrix diag( D ) + RHO * Z * transpose(Z) . The diagonal elements in the array D are assumed to satisfy D(i) < D(j) for i < j . We also assume RHO > 0 and that the Euclidean norm of the vector Z is one. Parameters: I I is INTEGER The index of the eigenvalue to be computed. I = 1 or I = 2. D D is DOUBLE PRECISION array, dimension (2) The original eigenvalues. We assume D(1) < D(2). Z Z is DOUBLE PRECISION array, dimension (2) The components of the updating vector. DELTA DELTA is DOUBLE PRECISION array, dimension (2) The vector DELTA contains the information necessary to construct the eigenvectors. RHO RHO is DOUBLE PRECISION The scalar in the symmetric updating formula. DLAM DLAM is DOUBLE PRECISION The computed lambda_I, the I-th updated eigenvalue.
