NAME
       dgesc2.f -

SYNOPSIS
   Functions/Subroutines
       subroutine dgesc2 (N, A, LDA, RHS, IPIV, JPIV, SCALE)
	   DGESC2 solves a system of linear equations using the LU factorization with complete pivoting computed by sgetc2.

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.
