NAME

       LAPACK-3  -  applies  an elementary permutation on the rows and the columns of a symmetric
       matrix

SYNOPSIS

       SUBROUTINE SSYSWAPR( UPLO, N, A, LDA, I1, I2)

           CHARACTER        UPLO

           INTEGER          I1, I2, LDA, N

           REAL             A( LDA, N )

PURPOSE

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

ARGUMENTS

        UPLO    (input) 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       (input) INTEGER
                The order of the matrix A.  N >= 0.

        A       (input/output) REAL 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 SSYTRF.
                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     (input) INTEGER
                The leading dimension of the array A.  LDA >= max(1,N).

        I1      (input) INTEGER
                Index of the first row to swap

        I2      (input) INTEGER
                Index of the second row to swap
