Function/Subroutine Documentation
subroutine zheswapr (characterUPLO, integerN, complex*16, dimension( lda, n )A, integerLDA,
integerI1, integerI2)
ZHESWAPR applies an elementary permutation on the rows and columns of a Hermitian matrix.
Purpose:
ZHESWAPR 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*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 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
