Detailed Description

template<typename BaseTy, typename NestedRegion, class ViewedElemT>
class sycl::_V1::ext::intel::esimd::simd_view< BaseTy, std::pair< region1d_scalar_t< ViewedElemT >, NestedRegion > >

This is a specialization of nested simd_view class with a single element.

Objects of such a class are created in the following situation: simd<int, 4> v = 1; auto v1 = v.select<2, 1>(0); auto v2 = v1[0]; // simd_view of a nested region for a single element
