Function Documentation
◆ broadcast()
template<Elem E, unsigned Elems = native_vector_length_v<E>>
vector< operand_base_type_t< E >, Elems > aie::broadcast | ( | E | a | ) |
Returns a vector whose elements are initialized to the given value.
for (unsigned i = 0; i < Elems; ++i)
out[i] = a;
- Template Parameters
-
E. Element type of the returned vector. Elems. Size of the vector.
- Parameters
-
a Value. The type must meet Elem.
◆ concat() [1/2]
template<Accum Acc, Accum... Accums>
requires ((is_same_accum_v<Acc, Accums> && ...))
requires ((is_same_accum_v<Acc, Accums> && ...))
auto aie::concat | ( | const Acc & | acc, |
const Accums &... | accums | ||
) | -> accum<typename Acc::value_type, Acc::size() * (1 + sizeof...(Accums))> |
Concatenate the contents of all input accumulators into a larger accumulator.
All input accumulators must have the same type and size.
- Parameters
-
acc First input accumulator. accums Rest of input accumulators.
◆ concat() [2/2]
template<Vector Vec, Vector... Vectors>
requires ((is_same_vector_v<Vec, Vectors> && ...))
requires ((is_same_vector_v<Vec, Vectors> && ...))
auto aie::concat | ( | const Vec & | v, |
const Vectors &... | vectors | ||
) | -> vector<typename Vec::value_type, Vec::size() * (1 + sizeof...(Vectors))> |
Concatenate the contents of all input vectors into a larger vector.
All input vectors must have the same type and size.
- Parameters
-
v First input vector. vectors Rest of input vectors.
◆ zeros()
template<ElemBaseType T, unsigned Elems = native_vector_length_v<T>>
vector< T, Elems > aie::zeros | ( | ) |
Returns a vector whose elements are initialized to zero.
for (unsigned i = 0; i < Elems; ++i)
out[i] = 0;
- Template Parameters
-
E. Element type of the returned vector. Elems. Size of the vector.
