DGET54 checks a generalized decomposition of the form


          A = U*S*V'  and B = U*T* V'


 where ' means transpose and U and V are orthogonal.


 Specifically,


  RESULT = ||( A - U*S*V', B - U*T*V' )|| / (||( A, B )||*n*ulp )

N

          N is INTEGER


          The size of the matrix.  If it is zero, DGET54 does nothing.


          It must be at least zero.

A

          A is DOUBLE PRECISION array, dimension (LDA, N)


          The original (unfactored) matrix A.

LDA

          LDA is INTEGER


          The leading dimension of A.  It must be at least 1


          and at least N.

B

          B is DOUBLE PRECISION array, dimension (LDB, N)


          The original (unfactored) matrix B.

LDB

          LDB is INTEGER


          The leading dimension of B.  It must be at least 1


          and at least N.

S

          S is DOUBLE PRECISION array, dimension (LDS, N)


          The factored matrix S.

LDS

          LDS is INTEGER


          The leading dimension of S.  It must be at least 1


          and at least N.

T

          T is DOUBLE PRECISION array, dimension (LDT, N)


          The factored matrix T.

LDT

          LDT is INTEGER


          The leading dimension of T.  It must be at least 1


          and at least N.

U

          U is DOUBLE PRECISION array, dimension (LDU, N)


          The orthogonal matrix on the left-hand side in the


          decomposition.

LDU

          LDU is INTEGER


          The leading dimension of U.  LDU must be at least N and


          at least 1.

V

          V is DOUBLE PRECISION array, dimension (LDV, N)


          The orthogonal matrix on the left-hand side in the


          decomposition.

LDV

          LDV is INTEGER


          The leading dimension of V.  LDV must be at least N and


          at least 1.

WORK

          WORK is DOUBLE PRECISION array, dimension (3*N**2)

RESULT

          RESULT is DOUBLE PRECISION


          The value RESULT, It is currently limited to 1/ulp, to


          avoid overflow. Errors are flagged by RESULT=10/ulp.
