generate_n() [1/2] template<typename DerivedPolicy , typename OutputIterator , typename Size , typename Generator > __host__ __device__ OutputIterator thrust::generate_n ( const thrust::detail::execution_policy_base< DerivedPolicy > &  exec, OutputIterator  first, Size  n, Generator  gen  ) generate_n assigns the result of invoking gen, a function object that takes no arguments, to each element in the range [first,first + n). The return value is first + n. The algorithm's execution is parallelized as determined by exec. Parameters exec The execution policy to use for parallelization. first The first element in the range of interest. n The size of the range of interest. gen A function argument, taking no parameters, used to generate values to assign to elements in the range [first,first + n). Template Parameters DerivedPolicy The name of the derived execution policy. OutputIterator is a model of Output Iterator. Size is an integral type (either signed or unsigned). Generator is a model of Generator, and Generator's result_type is convertible to a type in OutputIterator's set of value_types. The following code snippet demonstrates how to fill a host_vector with random numbers, using the standard C library function rand using the thrust::host execution policy for parallelization: #include <thrust/generate.h> #include <thrust/host_vector.h> #include <thrust/execution_policy.h> #include <cstdlib> ... thrust::host_vector<int> v(10); srand(13); thrust::generate_n(thrust::host, v.begin(), 10, rand); // the elements of v are now pseudo-random numbers See also generate https://en.cppreference.com/w/cpp/algorithm/generate
