RedHat 9 (Linux i386) - man page for zlarfx (redhat section l)

ZLARFX(l)					)					ZLARFX(l)

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

SYNOPSIS
       SUBROUTINE ZLARFX( SIDE, M, N, V, TAU, C, LDC, WORK )

	   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
       SIDE    (input) CHARACTER*1
	       = 'L': form  H * C
	       = 'R': form  C * H

       M       (input) INTEGER
	       The number of rows of the matrix C.

       N       (input) INTEGER
	       The number of columns of the matrix C.

       V       (input) COMPLEX*16 array, dimension (M) if SIDE = 'L'
	       or (N) if SIDE = 'R' The vector v in the representation of H.

       TAU     (input) COMPLEX*16
	       The value tau in the representation of H.

       C       (input/output) COMPLEX*16 array, dimension (LDC,N)
	       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'.

       LDC     (input) INTEGER
	       The leading dimension of the array C. LDA >= max(1,M).

       WORK    (workspace) COMPLEX*16 array, dimension (N) if SIDE = 'L'
	       or (M) if SIDE = 'R' WORK is not referenced if H has order < 11.
