NAME
       cgesc2.f -

SYNOPSIS
   Functions/Subroutines
       subroutine cgesc2 (N, A, LDA, RHS, IPIV, JPIV, SCALE)
	   CGESC2 solves a system of linear equations using the LU factorization with complete
	   pivoting computed by sgetc2.

Function/Subroutine Documentation
   subroutine cgesc2 (integerN, complex, dimension( lda, * )A, integerLDA, complex, dimension( *
       )RHS, integer, dimension( * )IPIV, integer, dimension( * )JPIV, realSCALE)
       CGESC2 solves a system of linear equations using the LU factorization with complete
       pivoting computed by sgetc2.

       Purpose:

	    CGESC2 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 CGETC2.

       Parameters:
	   N

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

	   A

		     A is COMPLEX array, dimension (LDA, N)
		     On entry, the  LU part of the factorization of the n-by-n
		     matrix A computed by CGETC2:  A = P * L * U * Q

	   LDA

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

	   RHS

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