!>
!> CLATTR 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.
!> 

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.
!> 

A

!>          A is COMPLEX 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 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
