cusp::divide_pair_functor< T > Struct Template Reference

Detailed description

template<typename T>
struct cusp::divide_pair_functor< T >

divide_pair_functor is a function object that divides the first element of a 2 element tuple by the second element.

Tis a model of Assignable, and if x is an object of type thrust::tuple<T,T>, then x=c must be defined and must have a return type that is convertible to T.
divide_pair_functor is a function object. Specifically, it is an Adaptable Unary Function. If f(c) is an object of class divide_pair_functor<T>, and x is an object of class thrust::tuple<T,T>, then f(x) returns thrust::get<0>(x) / thrust::get<1>(x).

int main()
// create an array with 5 entries all containing 2
// create an array with 5 entries from -2 to 2
cusp::counting_array<float> counting(5, -2);
// allocate size of transformed output array
// compute output vector as transform of tens
thrust::transform(thrust::make_zip_iterator(thrust::make_tuple(counting.begin(), twos.begin())),
thrust::make_zip_iterator(thrust::make_tuple(counting.begin(), twos.begin())) + v.size(),
// v = [-1, 0, 1, 2, 3]
