SLSETS

Purpose:

 SLSETS tests SGGLSE - 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 REAL array, dimension (LDA,N)
          The M-by-N matrix A.

AF

          AF is REAL 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 REAL array, dimension (LDB,N)
          The P-by-N matrix A.

BF

          BF is REAL array, dimension (LDB,N)

LDB

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

C

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

CF

          CF is REAL array, dimension( M )

D

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

DF

          DF is REAL array, dimension( P )

X

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

WORK

          WORK is REAL array, dimension (LWORK)

LWORK

          LWORK is INTEGER
          The dimension of the array WORK.

RWORK

          RWORK is REAL array, dimension (M)

RESULT

          RESULT is REAL 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
