ZRZT01

Purpose:

    !>
    !> ZRZT01 returns
    !>      || A - R*Q || / ( M * eps * ||A|| )
    !> for an upper trapezoidal A that was factored with ZTZRZF.
    !>

Parameters
    M

    !>          M is INTEGER
    !>          The number of rows of the matrices A and AF.
    !>

    N

    !>          N is INTEGER
    !>          The number of columns of the matrices A and AF.
    !>

    A

    !>          A is COMPLEX*16 array, dimension (LDA,N)
    !>          The original upper trapezoidal M by N matrix A.
    !>

    AF

    !>          AF is COMPLEX*16 array, dimension (LDA,N)
    !>          The output of ZTZRZF for input matrix A.
    !>          The lower triangle is not referenced.
    !>

    LDA

    !>          LDA is INTEGER
    !>          The leading dimension of the arrays A and AF.
    !>

    TAU

    !>          TAU is COMPLEX*16 array, dimension (M)
    !>          Details of the  Householder transformations as returned by
    !>          ZTZRZF.
    !>

    WORK

    !>          WORK is COMPLEX*16 array, dimension (LWORK)
    !>

    LWORK

    !>          LWORK is INTEGER
