NAME

       LAPACK-3  -  applies  a  complex elementary reflector H to a complex m by n matrix C, from
       either the left or the right

SYNOPSIS

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

           IMPLICIT       NONE

           CHARACTER      SIDE

           INTEGER        LDC, M, N

           COMPLEX        TAU

           COMPLEX        C( LDC, * ), V( * ), WORK( * )

PURPOSE

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

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

        C       (input/output) COMPLEX 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 array, dimension (N) if SIDE = 'L'
                or (M) if SIDE = 'R'
                WORK is not referenced if H has order < 11.
