span

Header: <pressio/expressions.hpp>

API

namespace pressio {

template<class T>
/*impl defined*/ span(T & operand,
                      std::pair<std::size_t, std::size_t> indexRange);

} // end namespace pressio

Description

• Takes in an operand and an indexRange

  • operand is either:

    • an Eigen vector object: pressio::is_vector_eigen<T>::value == true

    • a Kokkos rank-1 view, i.e. pressio::is_vector_kokkos<T>::value == true

  • indexRange is a std::pairidentifying an interval [a, b) where the second index is exclusive

• Returns an expression that represents the target span of the operand.
