thrust::tabulate
Defined in thrust/tabulate.h
-
template<typename ForwardIterator, typename UnaryOperation>
void thrust::tabulate(ForwardIterator first, ForwardIterator last, UnaryOperation unary_op) tabulatefills the range[first, last)with the value of a function applied to each element’s index.For each iterator
iin the range[first, last),tabulateperforms the assignment*i = unary_op(i - first).The following code snippet demonstrates how to use
tabulateto generate the firstnnon-positive integers:#include <thrust/tabulate.h> #include <thrust/functional.h> ... const int N = 10; int A[N]; thrust::tabulate(A, A + 10, thrust::negate<int>()); // A is now {0, -1, -2, -3, -4, -5, -6, -7, -8, -9}

- Parameters
first – The beginning of the range.
last – The end of the range.
unary_op – The unary operation to apply.
- Template Parameters
ForwardIterator – is a model of Forward Iterator, and
ForwardIteratoris mutable, and ifxandyare objects ofForwardIterator'svalue_type, thenx + yis defined, and ifTisForwardIterator'svalue_type, thenT(0)is defined.UnaryOperation – The function’s return type must be convertible to
OutputIterator'svalue_type.
