thrust::sequence

Defined in thrust/sequence.h

template<typename DerivedPolicy, typename ForwardIterator, typename T> void thrust::sequence(const thrust::detail::execution_policy_base<DerivedPolicy> &exec, ForwardIterator first, ForwardIterator last, T init, T step)

sequence fills the range [first, last) with a sequence of numbers.

For each iterator i in the range [first, last), this version of sequence performs the assignment *i = init + step * (i - first).

The algorithm’s execution is parallelized as determined by exec.

The following code snippet demonstrates how to use sequence to fill a range with a sequence of numbers starting from the value 1 with a step size of 3 using the thrust::host execution policy for parallelization:

#include <thrust/sequence.h>
#include <thrust/execution_policy.h>
...
const int N = 10;
int A[N];
thrust::sequence(thrust::host, A, A + 10, 1, 3);
// A is now {1, 4, 7, 10, 13, 16, 19, 22, 25, 28}
