subroutine zsyswapr (UPLO, N, A, LDA, I1, I2)
subroutine zsyswapr (characterUPLO, integerN, complex*16, dimension( lda, n )A, integerLDA, integerI1, integerI2)
ZSYSWAPR applies an elementary permutation on the rows and the columns of a symmetric matrix.
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 is INTEGER The order of the matrix A. N >= 0.
A is COMPLEX*16 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 ZSYTRF. 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 is INTEGER The leading dimension of the array A. LDA >= max(1,N).
I1 is INTEGER Index of the first row to swap
I2 is INTEGER Index of the second row to swap
