Detailed Description

template<typename BaseTy, typename RegionTy = region1d_t<typename BaseTy::element_type, BaseTy::length, 1>>
class sycl::_V1::ext::intel::esimd::simd_view< BaseTy, RegionTy >

This class represents a reference to a sub-region of a base simd object.

The referenced sub-region of the base object can be read from and written to via an instance of this class. Derives from detail::simd_view_impl, which defines the majority of available APIs for view classes.

User code is never supposed to explicitly provide actual template parameters for this class. They are always auto-deduced or provided by APIs.

Template Parameters

BaseTy	The base type - type of the object viewed by this one.
RegionTy	Describes the viewed region - its shape and element type. Regions can be 1D and 2D.
