array_view::section Method

Returns a subsection of the array_view object that's at the specified origin and, optionally, that has the specified extent.

array_view section(
   const Concurrency::index<_Rank>& _Section_origin,
   const Concurrency::extent<_Rank>& _Section_extent
) const restrict(amp,cpu);

array_view section(
   const Concurrency::index<_Rank>& _Idx
) const restrict(amp,cpu);

array_view section(
   const Concurrency::extent<_Rank>& _Ext
) const restrict(amp,cpu);

array_view section(
   int _I0,
   int _E0
) const restrict(amp,cpu);

array_view section(
   int _I0,
   int _I1,
   int _E0,
   int _E1
) const restrict(amp,cpu);

array_view section(
   int _I0,
   int _I1,
   int _I2,
   int _E0,
   int _E1,
   int _E2
) const restrict(amp,cpu);

Parameters

• _E0
  The most significant component of the extent of this section.

• _E1
  The next-to-most-significant component of the extent of this section.

• _E2
  The least significant component of the extent of this section.

• _Ext
  The extent object that specifies the extent of the section. The origin is 0.

• _Idx
  The index object that specifies the location of the origin. The subsection is the rest of the extent.

• _I0
  The most significant component of the origin of this section.

• _I1
  The next-to-most-significant component of the origin of this section.

• _I2
  The least significant component of the origin of this section.

• _Rank
  The rank of the section.

• _Section_extent
  The extent object that specifies the extent of the section.

• _Section_origin
  The index object that specifies the location of the origin.

Return Value

A subsection of the array_view object that's at the specified origin and, optionally, that has the specified extent. When only the index object is specified, the subsection contains all elements in the associated extent that have indexes that are larger than the indexes of the elements in the index object.
