NAME
       dsyswapr.f -

SYNOPSIS
   Functions/Subroutines
       subroutine dsyswapr (UPLO, N, A, LDA, I1, I2)
	   DSYSWAPR applies an elementary permutation on the rows and columns
	   of a symmetric matrix.

Function/Subroutine Documentation
   subroutine dsyswapr (characterUPLO, integerN, double precision, dimension(
       lda, n )A, integerLDA, integerI1, integerI2)
       DSYSWAPR applies an elementary permutation on the rows and columns of a
       symmetric matrix.

       Purpose:

	    DSYSWAPR applies an elementary permutation on the rows and the columns of
	    a symmetric matrix.

       Parameters:
	   UPLO

		     UPLO is CHARACTER*1
		     Specifies whether the details of the factorization are stored
		     as an upper or lower triangular matrix.
		     = 'U':  Upper triangular, form is A = U*D*U**T;
		     = 'L':  Lower triangular, form is A = L*D*L**T.

	   N

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

	   A

		     A is DOUBLE PRECISION array, dimension (LDA,N)
		     On entry, the NB diagonal matrix D and the multipliers
		     used to obtain the factor U or L as computed by DSYTRF.

		     On exit, if INFO = 0, the (symmetric) inverse of the original
		     matrix.  If UPLO = 'U', the upper triangular part of the
		     inverse is formed and the part of A below the diagonal is not
		     referenced; if UPLO = 'L' the lower triangular part of the
		     inverse is formed and the part of A above the diagonal is
		     not referenced.

	   LDA

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

	   I1

		     I1 is INTEGER
		     Index of the first row to swap

	   I2

		     I2 is INTEGER
		     Index of the second row to swap
