SRC/ztpttr.f(3) Library Functions Manual SRC/ztpttr.f(3) NAME SRC/ztpttr.f SYNOPSIS Functions/Subroutines subroutine ztpttr (uplo, n, ap, a, lda, info) ZTPTTR copies a triangular matrix from the standard packed format (TP) to the standard full format (TR). Function/Subroutine Documentation subroutine ztpttr (character uplo, integer n, complex*16, dimension( * ) ap, complex*16, dimension( lda, * ) a, integer lda, integer info) ZTPTTR copies a triangular matrix from the standard packed format (TP) to the standard full format (TR). Purpose: ZTPTTR copies a triangular matrix A from standard packed format (TP) to standard full format (TR). Parameters UPLO UPLO is CHARACTER*1 = 'U': A is upper triangular. = 'L': A is lower triangular. N N is INTEGER The order of the matrix A. N >= 0. AP AP is COMPLEX*16 array, dimension ( N*(N+1)/2 ), On entry, 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. A A is COMPLEX*16 array, dimension ( LDA, N ) On exit, 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). 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.
