Syntax
------

**Buffer API**


.. code-block::


   template<method Method = method::fast, typename Type, layout ObservationsLayout>
   void central_sum(sycl::queue& queue,
       sycl::buffer<Type, 1> mean,
       const dataset<ObservationsLayout, sycl::buffer<Type, 1>>& data,
       sycl::buffer<Type, 1> central_sum_2,
       sycl::buffer<Type, 1> central_sum_3 = {0},
       sycl::buffer<Type, 1> central_sum_4 = {0});


**USM API**


.. code-block::
