thrust

◆ generate() [2/2]

template<typename ForwardIterator , typename Generator >
void thrust::generate ( ForwardIterator  first,
ForwardIterator  last,
Generator  gen 
)

generate assigns the result of invoking gen, a function object that takes no arguments, to each element in the range [first,last).

Parameters
firstThe first element in the range of interest.
lastThe last element in the range of interest.
genA function argument, taking no parameters, used to generate values to assign to elements in the range [first,last).
Template Parameters
ForwardIteratoris a model of Forward Iterator, and ForwardIterator is mutable.
Generatoris a model of Generator, and Generator's result_type is convertible to ForwardIterator's value_type.

The following code snippet demonstrates how to fill a host_vector with random numbers, using the standard C library function rand.

#include <cstdlib>
...
thrust::host_vector<int> v(10);
srand(13);
thrust::generate(v.begin(), v.end(), rand);
// the elements of v are now pseudo-random numbers
