    Purpose   
    =======   

    DLARFB applies a real block reflector H or its transpose H**T to a   
    real m by n matrix C, from either the left or the right.

    =========

            Indicates how the vectors which define the elementary   
            reflectors are stored:

            if SIDE = 'R', LDWORK >= max(1,M).   

    Further Details   
    ===============   

    The shape of the matrix V and the storage of the vectors which define   
    the H(i) is best illustrated by the following example with n = 5 and   
    k = 3. The elements equal to 1 are not stored; the corresponding   
    array elements are modified but restored on exit. The rest of the   
    array is not used.   

    DIRECT = 'F' and STOREV = 'C':         DIRECT = 'F' and STOREV = 'R':   

                 V = (  1       )                 V = (  1 v1 v1 v1 v1 )   
                     ( v1  1    )                     (     1 v2 v2 v2 )   
                     ( v1 v2  1 )                     (        1 v3 v3 )   
                     ( v1 v2 v3 )   
                     ( v1 v2 v3 )   

    DIRECT = 'B' and STOREV = 'C':         DIRECT = 'B' and STOREV = 'R':   

                 V = ( v1 v2 v3 )                 V = ( v1 v1  1       )   
                     ( v1 v2 v3 )                     ( v2 v2 v2  1    )   
                     (  1 v2 v3 )                     ( v3 v3 v3 v3  1 )
