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 CLARF( SIDE, M, N, V, INCV, TAU, C, LDC, WORK )

           IMPLICIT      NONE

           CHARACTER     SIDE

           INTEGER       INCV, LDC, M, N

           COMPLEX       TAU

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

PURPOSE

       CLARF 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.
        To apply H**H (the conjugate transpose of H), supply conjg(tau) instead
        tau.

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
                (1 + (M-1)*abs(INCV)) if SIDE = 'L'
                or (1 + (N-1)*abs(INCV)) if SIDE = 'R'
                The vector v in the representation of H. V is not used if
                TAU = 0.

        INCV    (input) INTEGER
                The increment between elements of v. INCV <> 0.

        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. LDC >= max(1,M).

        WORK    (workspace) COMPLEX array, dimension
                (N) if SIDE = 'L'
                or (M) if SIDE = 'R'
