SYNOPSIS
   Functions/Subroutines
       real function cqrt12 (m, n, a, lda, s, work, lwork, rwork)
           CQRT12

Function/Subroutine Documentation
   real function cqrt12 (integer m, integer n, complex, dimension( lda, * ) a,
       integer lda, real, dimension( * ) s, complex, dimension( lwork ) work,
       integer lwork, real, dimension( * ) rwork)
       CQRT12

       Purpose:


           !>
           !> CQRT12 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 is COMPLEX 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 REAL array, dimension (min(M,N))
           !>          The singular values of the matrix A.
           !>

           !>          max(M,N).
           !>

           RWORK

           !>          RWORK is REAL array, dimension (4*min(M,N))
