!>
!> CLATTB 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 (= 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.
!> 

KD

!>          KD is INTEGER
!>          The number of superdiagonals or subdiagonals of the banded
!>          triangular matrix A.  KD >= 0.
!> 

AB

!>          AB is COMPLEX array, dimension (LDAB,N)
!>          The upper or lower triangular banded matrix A, stored in the
!>          first KD+1 rows of AB.  Let j be a column of A, 1<=j<=n.
!>          If UPLO = 'U', AB(kd+1+i-j,j) = A(i,j) for max(1,j-kd)<=i<=j.
!>          If UPLO = 'L', AB(1+i-j,j)    = A(i,j) for j<=i<=min(n,j+kd).
!> 

LDAB

!>          LDAB is INTEGER
!>          The leading dimension of the array AB.  LDAB >= KD+1.
!> 

B

!>          B is COMPLEX array, dimension (N)
!> 

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
