Function/Subroutine Documentation
   subroutine clattp (integer imat, character uplo, character trans, character
       diag, integer, dimension( 4 ) iseed, integer n, complex, dimension( * )

       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

           !>          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.
           !>
