zheswapr.f(3) LAPACK zheswapr.f(3)

zheswapr.f -


subroutine zheswapr (UPLO, N, A, LDA, I1, I2)
 
ZHESWAPR applies an elementary permutation on the rows and columns of a Hermitian matrix.

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
