thrust

◆ sequence() [6/6]

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

Parameters
firstThe beginning of the sequence.
lastThe end of the sequence.
initThe first value of the sequence of numbers
stepThe difference between consecutive elements.
Template Parameters
ForwardIteratoris 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.
Tis a model of Assignable, and T is convertible to ForwardIterator's value_type.

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.

...
const int N = 10;
int A[N];
thrust::sequence(A, A + 10, 1, 3);
// A is now {1, 4, 7, 10, 13, 16, 19, 22, 25, 28}
Note
Unlike the similar C++ STL function std::iota, sequence offers no guarantee on order of execution.
