CHESWAPR applies an elementary permutation on the rows and columns
of a Hermitian matrix.

Function/Subroutine Documentation
subroutine cheswapr (characterUPLO, integerN, complex, dimension( lda, n
)A, integerLDA, integerI1, integerI2)
CHESWAPR applies an elementary permutation on the rows and columns of a
Hermitian matrix.

Purpose:

CHESWAPR applies an elementary permutation on the rows and the columns of
a hermitian 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 COMPLEX 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 CSYTRF.

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
