SRC/cheswapr.f(3) Library Functions Manual SRC/cheswapr.f(3) NAME SRC/cheswapr.f SYNOPSIS Functions/Subroutines subroutine cheswapr (uplo, n, a, lda, i1, i2) CHESWAPR applies an elementary permutation on the rows and columns of a Hermitian matrix. Function/Subroutine Documentation subroutine cheswapr (character uplo, integer n, complex, dimension( lda, n ) a, integer lda, integer i1, integer i2) 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 Author Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.
