NAME
       TESTING/LIN/dqrt12.f

SYNOPSIS
   Functions/Subroutines
       double precision function dqrt12 (m, n, a, lda, s, work, lwork)
           DQRT12

Function/Subroutine Documentation
   double precision function dqrt12 (integer m, integer n, double precision,
       dimension( lda, * ) a, integer lda, double precision, dimension( * ) s,
       double precision, dimension( lwork ) work, integer lwork)
       DQRT12

       Purpose:


            DQRT12 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
                     The number of columns of the matrix A.

           A

                     A is DOUBLE PRECISION 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 DOUBLE PRECISION array, dimension (LWORK)

           LWORK

                     LWORK is INTEGER
                     The length of the array WORK. LWORK >= max(M*N + 4*min(M,N) +
                     max(M,N), M*N+2*MIN( M, N )+4*N).
