dsyswapr.f - SYNOPSIS
Functions/Subroutines subroutine dsyswapr (UPLO, N, A, LDA, I1, I2) DSYSWAPR Function/Subroutine Documentation subroutine dsyswapr (characterUPLO, integerN, double precision, dimension( lda, n )A, integerLDA, integerI1, integerI2) DSYSWAPR Purpose: DSYSWAPR applies an elementary permutation on the rows and the columns of a symmetric 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 DOUBLE PRECISION 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 DSYTRF. 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.
