ctrttp.f(3) LAPACK ctrttp.f(3) NAME
ctrttp.f - SYNOPSIS
Functions/Subroutines subroutine ctrttp (UPLO, N, A, LDA, AP, INFO) CTRTTP Function/Subroutine Documentation subroutine ctrttp (characterUPLO, integerN, complex, dimension( lda, * )A, integerLDA, complex, dimension( * )AP, integerINFO) CTRTTP Purpose: CTRTTP copies a triangular matrix A from full format (TR) to standard packed format (TP). Parameters: UPLO UPLO is CHARACTER*1 = 'U': A is upper triangular; = 'L': A is lower triangular. N N is INTEGER The order of the matrices AP and A. N >= 0. A A is COMPLEX array, dimension (LDA,N) On entry, the triangular matrix A. If UPLO = 'U', the leading N-by-N upper triangular part of A contains the upper triangular part of the matrix A, and the strictly lower triangular part of A is not referenced. If UPLO = 'L', the leading N-by-N lower triangular part of A contains the lower triangular part of the matrix A, and the strictly upper triangular part of A is not referenced. LDA LDA is INTEGER The leading dimension of the array A. LDA >= max(1,N). AP AP is COMPLEX array, dimension ( N*(N+1)/2 ), On exit, the upper or lower triangular matrix A, packed columnwise in a linear array. The j-th column of A is stored in the array AP as follows: if UPLO = 'U', AP(i + (j-1)*j/2) = A(i,j) for 1<=i<=j; if UPLO = 'L', AP(i + (j-1)*(2n-j)/2) = A(i,j) for j<=i<=n. INFO INFO is INTEGER = 0: successful exit < 0: if INFO = -i, the i-th argument had an illegal value Author: Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.
