SYNOPSIS
Functions/Subroutines subroutine zlarfgp (N, ALPHA, X, INCX, TAU) ZLARFGP generates an elementary reflector (Householder matrix) with non-negatibe beta. Function/Subroutine Documentation subroutine zlarfgp (integerN, complex*16ALPHA, complex*16, dimension( * )X, integerINCX, complex*16TAU) ZLARFGP generates an elementary reflector (Householder matrix) with non-negatibe beta. Purpose: ZLARFGP generates a complex elementary reflector H of order n, such that H**H * ( alpha ) = ( beta ), H**H * H = I. ( x ) ( 0 ) where alpha and beta are scalars, beta is real and non-negative, and x is an (n-1)-element complex vector. H is represented in the form H = I - tau * ( 1 ) * ( 1 v**H ) , ( v ) where tau is a complex scalar and v is a complex (n-1)-element vector. Note that H is not hermitian. If the elements of x are all zero and alpha is real, then tau = 0 and H is taken to be the unit matrix. Parameters: N N is INTEGER The order of the elementary reflector. ALPHA ALPHA is COMPLEX*16 On entry, the value alpha. On exit, it is overwritten with the value beta. X X is COMPLEX*16 array, dimension (1+(N-2)*abs(INCX)) On entry, the vector x. On exit, it is overwritten with the vector v. INCX INCX is INTEGER The increment between elements of X. INCX > 0. TAU TAU is COMPLEX*16 The value tau.
