Function/Subroutine Documentation

   subroutine dgesc2 (integerN, double precision, dimension( lda, * )A, integerLDA, double
       precision, dimension( * )RHS, integer, dimension( * )IPIV, integer, dimension( * )JPIV,
       double precisionSCALE)
       DGESC2 solves a system of linear equations using the LU factorization with complete
       pivoting computed by sgetc2.

       Purpose:

            DGESC2 solves a system of linear equations

                      A * X = scale* RHS

            with a general N-by-N matrix A using the LU factorization with
            complete pivoting computed by DGETC2.

       Parameters:
           N

                     N is INTEGER
                     The order of the matrix A.

           A

                     A is DOUBLE PRECISION array, dimension (LDA,N)
                     On entry, the  LU part of the factorization of the n-by-n
                     matrix A computed by DGETC2:  A = P * L * U * Q

           LDA

                     LDA is INTEGER
                     The leading dimension of the array A.  LDA >= max(1, N).

           RHS

                     RHS is DOUBLE PRECISION array, dimension (N).
                     On entry, the right hand side vector b.
                     On exit, the solution vector X.

           IPIV

                     IPIV is INTEGER array, dimension (N).
                     The pivot indices; for 1 <= i <= N, row i of the
                     matrix has been interchanged with row IPIV(i).

           JPIV

                     JPIV is INTEGER array, dimension (N).
                     The pivot indices; for 1 <= j <= N, column j of the
                     matrix has been interchanged with column JPIV(j).

           SCALE

                     SCALE is DOUBLE PRECISION
                     On exit, SCALE contains the scale factor. SCALE is chosen
                     0 <= SCALE <= 1 to prevent owerflow in the solution.
