thrust::transform_n

Defined in thrust/transform.h

template<typename InputIterator1, typename InputIterator2, typename OutputIterator, typename BinaryFunction>
OutputIterator thrust::transform_n(InputIterator1 first1, ::cuda::std::iter_difference_t<InputIterator1> count, InputIterator2 first2, OutputIterator result, BinaryFunction op)

Like transform, but uses an element count instead of an iterator to the last element of the input sequence.
