\details
TPSV_BATCHED solves

     A_ix_i = b_i or A_iTx_i = b_i, or A_iHx_i = b_i,

where x_i and b_i are vectors and A_i is a triangular matrix stored in the packed format,
for i in [1, batch_count].

The input vectors b_i are overwritten by the output vectors x_i.

@param[in]
handle    [rocblas_handle]
          handle to the rocblas library context queue.

@param[in]
uplo    [rocblas_fill]
        rocblas_fill_upper:  each A_i is an upper triangular matrix.
        rocblas_fill_lower:  each A_i is a  lower triangular matrix.

@param[in]
transA  [rocblas_operation]
        rocblas_operation_none: Solves Ax = b
        rocblas_operation_transpose: Solves ATx = b
        rocblas_operation_conjugate_transpose: Solves AHx = b

@param[in]
diag    [rocblas_diagonal]
        rocblas_diagonal_unit:     each A_i is assumed to be unit triangular (i.e. the diagonal elements
                                   of each A_i are not used in computations).
        rocblas_diagonal_non_unit: each A_i is not assumed to be unit triangular.

@param[in]
n         [rocblas_int]
          n specifies the number of rows of each b_i. n >= 0.

@param[in]
AP        device array of device pointers storing the packed versions of each matrix A_i,
          of dimension >= (n  (n + 1)  2)

@param[inout]
x         device array of device pointers storing each input vector b_i, overwritten by x_i on output.

@param[in]
incx      [rocblas_int]
          specifies the increment for the elements of each x_i.
@param[in]
batch_count [rocblas_int]
            specifies the number of instances in the batch.
