adjacent_difference() [2/4] template<typename DerivedPolicy , typename InputIterator , typename OutputIterator , typename BinaryFunction > __host__ __device__ OutputIterator thrust::adjacent_difference ( const thrust::detail::execution_policy_base< DerivedPolicy > &  exec, InputIterator  first, InputIterator  last, OutputIterator  result, BinaryFunction  binary_op  ) adjacent_difference calculates the differences of adjacent elements in the range [first, last). That is, *first is assigned to *result, and, for each iterator i in the range [first + 1, last), binary_op(*i, *(i - 1)) is assigned to *(result + (i - first)). This version of adjacent_difference uses the binary function binary_op to calculate differences. The algorithm's execution is parallelized as determined by exec. Parameters exec The execution policy to use for parallelization. first The beginning of the input range. last The end of the input range. result The beginning of the output range. binary_op The binary function used to compute differences. Returns The iterator result + (last - first) Template Parameters DerivedPolicy The name of the derived execution policy. InputIterator is a model of Input Iterator, and InputIterator's value_type is convertible to BinaryFunction's first_argument_type and second_argument_type, and InputIterator's value_type is convertible to a type in OutputIterator's set of value_types. OutputIterator is a model of Output Iterator. BinaryFunction's result_type is convertible to a type in OutputIterator's set of value_types. Remarks Note that result is permitted to be the same iterator as first. This is useful for computing differences "in place". The following code snippet demonstrates how to use adjacent_difference to compute the sum between adjacent elements of a range using the thrust::device execution policy: #include <thrust/adjacent_difference.h> #include <thrust/functional.h> #include <thrust/device_vector.h> #include <thrust/execution_policy.h> ... int h_data[8] = {1, 2, 1, 2, 1, 2, 1, 2}; thrust::device_vector<int> d_data(h_data, h_data + 8); thrust::device_vector<int> d_result(8); thrust::adjacent_difference(thrust::device, d_data.begin(), d_data.end(), d_result.begin(), thrust::plus<int>()); // d_result is now [1, 3, 3, 3, 3, 3, 3, 3] See also http://www.sgi.com/tech/stl/adjacent_difference.html inclusive_scan
