cusp::square_functor< T > Struct Template Reference

Detailed description

template<typename T>
struct cusp::square_functor< T >

square_functor is a function object that computes the square (x*x) of a given element.

Tis a model of Assignable, and if x is an object of type T, then x*c must be defined and must have a return type that is convertible to T.
square_functor is a function object. Specifically, it is an Adaptable Unary Function. If f(c) is an object of class square_functor<T>, and x is an object of class T, then f(x) returns x*x.
#include <cusp/array1d.h>

int main()
// create an array with 5 entries from 0 to 4
// allocate size of transformed output array
// compute output vector as transform of tens
thrust::transform(count.begin(), count.end(), v.begin(), cusp::square_functor<int>());
// v = [0, 1, 4, 9, 16]
