ssyconv.f-SYNOPSIS

Functions/Subroutines subroutine ssyconv (UPLO, WAY, N, A, LDA, IPIV, WORK, INFO) SSYCONVFunction/Subroutine Documentation subroutine ssyconv (characterUPLO, characterWAY, integerN, real, dimension( lda, * )A, integerLDA, integer, dimension( * )IPIV, real, dimension( * )WORK, integerINFO) SSYCONV Purpose: SSYCONV convert A given by TRF into L and D and vice-versa. Get Non-diag elements of D (returned in workspace) and apply or reverse permutation done in TRF. 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. WAY WAY is CHARACTER*1 = 'C': Convert = 'R': Revert N N is INTEGER The order of the matrix A. N >= 0. A A is REAL array, dimension (LDA,N) The block diagonal matrix D and the multipliers used to obtain the factor U or L as computed by SSYTRF. LDA LDA is INTEGER The leading dimension of the array A. LDA >= max(1,N). IPIV IPIV is INTEGER array, dimension (N) Details of the interchanges and the block structure of D as determined by SSYTRF.
