// or any other executor CPUExecutor, SerialExecutor
NeoN::Executor = NeoN::GPUExecutor{};
NeoN::Vector<NeoN::scalar> fieldA(exec, 2);
NeoN::Vector<NeoN::scalar> fieldB(exec, 2, 1.0);
NeoN::Vector<NeoN::scalar> fieldC(exec, 2, 2.0);
// Note if the executor does not match the program will exit with a segfault
NeoN::setVector(field, fieldB.view());
// only set the last element of the field
NeoN::map(field, fieldC.view(), {1, 2});
// copy to host
auto hostVector = field.copyToHost();
for (auto i = 0; i < field.size(); ++i)
{
std::cout << hostVector[i] << std::endl;
}
// prints:
// 1.0
// 2.0
