DLSETS

Purpose:

 DLSETS tests DGGLSE - a subroutine for solving linear equality
 constrained least square problem (LSE).

Parameters

M

          M is INTEGER
          The number of rows of the matrix A.  M >= 0.

P

          P is INTEGER
          The number of rows of the matrix B.  P >= 0.

N

          N is INTEGER
          The number of columns of the matrices A and B.  N >= 0.

A

          A is DOUBLE PRECISION array, dimension (LDA,N)
          The M-by-N matrix A.

AF

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

LDA

          LDA is INTEGER
          The leading dimension of the arrays A, AF, Q and R.
          LDA >= max(M,N).

B

          B is DOUBLE PRECISION array, dimension (LDB,N)
          The P-by-N matrix A.

BF

LDB

          LDB is INTEGER
          The leading dimension of the arrays B, BF, V and S.
          LDB >= max(P,N).

C

          C is DOUBLE PRECISION array, dimension( M )
          the vector C in the LSE problem.

CF

          CF is DOUBLE PRECISION array, dimension( M )

D

          D is DOUBLE PRECISION array, dimension( P )
          the vector D in the LSE problem.

DF

          DF is DOUBLE PRECISION array, dimension( P )

X

          X is DOUBLE PRECISION array, dimension( N )
          solution vector X in the LSE problem.

WORK

          WORK is DOUBLE PRECISION array, dimension (LWORK)

LWORK

          LWORK is INTEGER
          The dimension of the array WORK.

RWORK

          RWORK is DOUBLE PRECISION array, dimension (M)

RESULT

          RESULT is DOUBLE PRECISION array, dimension (2)
          The test ratios:
            RESULT(1) = norm( A*x - c )/ norm(A)*norm(X)*EPS
            RESULT(2) = norm( B*x - d )/ norm(B)*norm(X)*EPS
