ZLARFX(1) LAPACK auxiliary routine (version 3.2) ZLARFX(1)

NAME

ZLARFX - applies a complex elementary reflector H to a complex m by n matrix C, from either the left or the right

SYNOPSIS

SIDE, M, N, V, TAU, C, LDC, WORK )

IMPLICIT NONE CHARACTER SIDE INTEGER LDC, M, N COMPLEX*16 TAU COMPLEX*16 C( LDC, * ), V( * ), WORK( * )

PURPOSE

ZLARFX applies a complex elementary reflector H to a complex m by n matrix C, from either the left or the right. H is represented in the form
H = I - tau * v * v'
where tau is a complex scalar and v is a complex vector.
If tau = 0, then H is taken to be the unit matrix
This version uses inline code if H has order < 11.

ARGUMENTS

= 'L': form H * C
= 'R': form C * H
The number of rows of the matrix C.
The number of columns of the matrix C.
or (N) if SIDE = 'R' The vector v in the representation of H.
The value tau in the representation of H.
On entry, the m by n matrix C. On exit, C is overwritten by the matrix H * C if SIDE = 'L', or C * H if SIDE = 'R'.
The leading dimension of the array C. LDA >= max(1,M).
or (M) if SIDE = 'R' WORK is not referenced if H has order < 11.
