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.
