Splits the input simd or simd_mask object into multiple simd or simd_mask objects.

1-2) Split the input object into potentially different types (e.g. types with different sizes) of objects. These functions do not participate in overloading resolution unless Sizes... sum up to v.size().
3-4) Split the input object into an array of objects. These functions do not participate in overloading resolution unless
  • The array element must be of type simd or simd_mask, for the type of v as simd or simd_mask, respectively.
  • simd_size_v<typename V::value_type, Abi> is an integral multiple of V::size().
5-6) Split the input object into an array of objects. These functions shall not participate in overload resolution unless simd_size_v<T, A> is an integral multiple of N.

Parameters

v - the input simd or simd_mask object

Return value

1-2) A tuple that contains the splitted simd or simd_mask objects.
3-6) An array that contains the splitted simd or simd_mask objects.
