CLATTP
Purpose:
!> !> CLATTP generates a triangular test matrix in packed storage. !> IMAT and UPLO uniquely specify the properties of the test matrix, !> which is returned in the array AP. !>
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 !> CLATMS). Modified on exit. !>
N
!> N is INTEGER !> The order of the matrix to be generated. !>
AP
!> AP is COMPLEX array, dimension (N*(N+1)/2) !> 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((j-1)*j/2 + i) = A(i,j) for 1<=i<=j; !> if UPLO = 'L', !> AP((j-1)*(n-j) + j*(j+1)/2 + i-j) = A(i,j) for j<=i<=n. !>
B
!> B is COMPLEX array, dimension (N) !> The right hand side vector, if IMAT > 10. !>
WORK
!> WORK is COMPLEX array, dimension (2*N) !>
RWORK
!> RWORK is REAL array, dimension (N) !>
INFO
!> INFO is INTEGER !> = 0: successful exit !> < 0: if INFO = -i, the i-th argument had an illegal value !>
