Template Function thrust::sequence(ForwardIterator, ForwardIterator)

Function Documentation

template<typename ForwardIterator>
void thrust::sequence(ForwardIterator first, ForwardIterator last)

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 = (i - first).

The following code snippet demonstrates how to use

sequence to fill a range with a sequence of numbers.

Parameters

• first: The beginning of the sequence.

• last: The end of the sequence.

Template Parameters

• ForwardIterator: is a model of Forward Iterator, and ForwardIterator is mutable, and if x and y are objects of ForwardIterator's value_type, then x + y is defined, and if T is ForwardIterator's value_type, then T(0) is defined.

#include <thrust/sequence.h>
...
const int N = 10;
int A[N];
thrust::sequence(A, A + 10);
// A is now {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

Note

Unlike the similar C++ STL function std::iota, sequence offers no guarantee on order of execution.
