NAME
       TESTING/LIN/zqrt12.f

SYNOPSIS
   Functions/Subroutines
       double precision function zqrt12 (m, n, a, lda, s, work, lwork, rwork)
           ZQRT12

Function/Subroutine Documentation
   double precision function zqrt12 (integer m, integer n, complex*16,
       dimension( lda, * ) a, integer lda, double precision, dimension( * ) s,
       complex*16, dimension( lwork ) work, integer lwork, double precision,
       dimension( * ) rwork)
       ZQRT12

       Purpose:


           !>
           !> ZQRT12 computes the singular values `svlues' of the upper trapezoid
           !> of A(1:M,1:N) and returns the ratio
           !>
           !>      || svlues - s||/(||s||*eps*max(M,N))
           !>

       Parameters
           M

           !>          M is INTEGER
           !>          The number of rows of the matrix A.
           !>

           N

           !>          N is INTEGER

           A

           !>          A is COMPLEX*16 array, dimension (LDA,N)
           !>          The M-by-N matrix A. Only the upper trapezoid is referenced.
           !>

           LDA

           !>          LDA is INTEGER
           !>          The leading dimension of the array A.
           !>

           S

           !>          S is DOUBLE PRECISION array, dimension (min(M,N))
           !>          The singular values of the matrix A.
           !>

           WORK

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

           !>          max(M,N).
           !>

           RWORK
