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.
