NAME
       dgetc2.f -

SYNOPSIS
   Functions/Subroutines
       subroutine dgetc2 (N, A, LDA, IPIV, JPIV, INFO)
	   DGETC2 computes the LU factorization with complete pivoting of the general n-by-n matrix.

Function/Subroutine Documentation
   subroutine dgetc2 (integerN, double precision, dimension( lda, * )A, integerLDA, integer, dimension( * )IPIV, integer, dimension( * )JPIV,
       integerINFO)
       DGETC2 computes the LU factorization with complete pivoting of the general n-by-n matrix.

       Purpose:

	    DGETC2 computes an LU factorization with complete pivoting of the
	    n-by-n matrix A. The factorization has the form A = P * L * U * Q,
	    where P and Q are permutation matrices, L is lower triangular with
	    unit diagonal elements and U is upper triangular.

	    This is the Level 2 BLAS algorithm.

       Parameters:
	   N

		     N is INTEGER
		     The order of the matrix A. N >= 0.

	   A

		     A is DOUBLE PRECISION array, dimension (LDA, N)
		     On entry, the n-by-n matrix A to be factored.
		     On exit, the factors L and U from the factorization
		     A = P*L*U*Q; the unit diagonal elements of L are not stored.
		     If U(k, k) appears to be less than SMIN, U(k, k) is given the
		     value of SMIN, i.e., giving a nonsingular perturbed system.

	   LDA

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

	   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).

	   INFO

		     INFO is INTEGER
		      = 0: successful exit
		      > 0: if INFO = k, U(k, k) is likely to produce owerflow if
			   we try to solve for x in Ax = b. So U is perturbed to
			   avoid the overflow.
