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.

[edit] Parameters v - the input simd or simd_mask object [edit] 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.
