       diag, integer, dimension( 4 ) iseed, integer n, complex*16, dimension(
       lda, * ) a, integer lda, complex*16, dimension( * ) b, complex*16,

       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 is CHARACTER*1
           !>          Specifies whether the matrix A will be upper or lower
           !>          triangular.
           !>          = 'U':  Upper triangular
           !>          = 'L':  Lower triangular

           !>          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
