Function/Subroutine Documentation¶
subroutine ZLATTR (integer imat, character uplo, character trans, character diag, integer, dimension( 4 ) iseed, integer n, complex*16, dimension( lda, * ) a, integer lda, complex*16, dimension( * ) b, complex*16, dimension( * ) work, double precision, dimension( * ) rwork, integer info)¶
ZLATTR
Purpose:
!> !> ZLATTR generates a triangular test matrix in 2-dimensional storage. !> IMAT and UPLO uniquely specify the properties of the test matrix, !> which is returned in the array A. !>
Parameters
IMAT
!> IMAT is INTEGER !> An integer key describing which matrix to generate for this !> path. !>
UPLO
!> UPLO is CHARACTER*1 !> Specifies whether the matrix A will be upper or lower !> triangular. !> = 'U': Upper triangular !> = 'L': Lower triangular !>
TRANS
!> TRANS is CHARACTER*1 !> Specifies whether the matrix or its transpose will be used. !> = 'N': No transpose !> = 'T': Transpose !> = 'C': Conjugate transpose !>
DIAG
!> DIAG is CHARACTER*1 !> Specifies whether or not the matrix A is unit triangular. !> = 'N': Non-unit triangular !> = 'U': Unit triangular !>
ISEED
!> ISEED is INTEGER array, dimension (4) !> The seed vector for the random number generator (used in !> ZLATMS). Modified on exit. !>
N
!> N is INTEGER !> The order of the matrix to be generated. !>
A
!> A is COMPLEX*16 array, dimension (LDA,N) !> The triangular matrix A. If UPLO = 'U', the leading N x N !> upper triangular part of the array A contains the upper !> triangular matrix, and the strictly lower triangular part of !> A is not referenced. If UPLO = 'L', the leading N x N lower !> triangular part of the array A contains the lower triangular !> matrix 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). !>
B
!> B is COMPLEX*16 array, dimension (N) !> The right hand side vector, if IMAT > 10. !>
WORK
!> WORK is COMPLEX*16 array, dimension (2*N) !>
RWORK
!> RWORK is DOUBLE PRECISION array, dimension (N) !>
INFO
!> INFO is INTEGER !> = 0: successful exit !> < 0: if INFO = -i, the i-th argument had an illegal value !>
