template<typename... T_Args>

alpaka::Vec< T_Type, T_dim, T_Storage >::Vec ( T_Args const &... args )

inlineconstexpr

Constructor for N-dimensional vector.

Attention

This constructor allows implicit casts.

Parameters

args	value of each dimension, x,y,z,...

A constexpr vector should be initialized with {} instead of () because at least CUDA 11.6 has problems in cases where a compile time evaluation is required.

constexpr auto vec1 = Vec{ 1 };

template<typename T_Type, uint32_t T_dim, typename T_Storage = alpaka::ArrayStorage<T_Type, T_dim>>

template<std::integral auto dimToRemove>
requires (T_dim >= 2u)

Vec< type, T_dim - 1u > alpaka::Vec< T_Type, T_dim, T_Storage >::remove ( ) const

inlineconstexpr

Removes a component.

It is not allowed to call this method on a vector with the dimensionality of one.

Template Parameters

dimToRemove

index which shall be removed; range: [ 0; T_dim - 1 ]

Returns

vector with T_dim - 1 elements

rshrink() [1/2]

template<typename T_Type, uint32_t T_dim, typename T_Storage = alpaka::ArrayStorage<T_Type, T_dim>>

template<uint32_t T_numElements>

Vec< T_Type, T_numElements > alpaka::Vec< T_Type, T_dim, T_Storage >::rshrink ( ) const

inlineconstexpr

Shrink the number of elements of a vector.

Highest indices kept alive.

Template Parameters

T_numElements

New dimension of the vector.

Returns

First T_numElements elements of the origin vector

Definition at line 410 of file Vec.hpp.

rshrink() [2/2]

template<typename T_Type, uint32_t T_dim, typename T_Storage = alpaka::ArrayStorage<T_Type, T_dim>>

template<uint32_t T_numElements>

Vec< type, T_numElements > alpaka::Vec< T_Type, T_dim, T_Storage >::rshrink ( std::integral auto const startIdx ) const

inlineconstexpr

Shrink the number of elements of a vector.

Template Parameters

T_numElements

New dimension of the vector.

Parameters

startIdx

Index within the origin vector which will be the last element in the result.

Returns

T_numElements elements of the origin vector starting with the index startIdx. Indexing will wrapp around when the begin of the origin vector is reached.

Returns sum of all components.

Returns

sum of components

toString()

template<typename T_Type, uint32_t T_dim, typename T_Storage = alpaka::ArrayStorage<T_Type, T_dim>>

std::string alpaka::Vec< T_Type, T_dim, T_Storage >::toString ( std::string const separator = ",", std::string const enclosings = "{}" ) const

inline

create string out of the vector

Parameters

separator	string to separate components of the vector
enclosings	string with dim 2 to enclose vector dim == 0 ? no enclose symbols dim == 1 ? means enclose symbol begin and end are equal dim >= 2 ? letter[0] = begin enclose symbol letter[1] = end enclose symbol

example: .toString(";","|") -> |x;...;z| .toString(",","[]") -> [x,...,z]
