SYNOPSIS
   Functions/Subroutines
       subroutine zgesc2 (N, A, LDA, RHS, IPIV, JPIV, SCALE)
	   ZGESC2 solves a system of linear equations using the LU factorization with complete pivoting computed by sgetc2.

Function/Subroutine Documentation
   subroutine zgesc2 (integerN, complex*16, dimension( lda, * )A, integerLDA, complex*16, dimension( * )RHS, integer, dimension( * )IPIV, integer,
       dimension( * )JPIV, double precisionSCALE)
       ZGESC2 solves a system of linear equations using the LU factorization with complete pivoting computed by sgetc2.

       Purpose:

	    ZGESC2 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 ZGETC2.

       Parameters:
	   N

		     N is INTEGER
		     The number of columns of the matrix A.

	   A

		     A is COMPLEX*16 array, dimension (LDA, N)
		     On entry, the  LU part of the factorization of the n-by-n
		     matrix A computed by ZGETC2:  A = P * L * U * Q

	   LDA

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

	   RHS

		     RHS is COMPLEX*16 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.
