cusp::multiplies_value< T > Struct Template Reference

Detailed description

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

multiplies_value is a function object that computes the multiply of a given element by a constant value.

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.
multiplies_value is a function object. Specifically, it is an Adaptable Unary Function. If f(c) is an object of class multiplies_value<T>, and x is an object of class T, then f(x) returns x*c.
#include <cusp/array1d.h>
#include <cusp/print.h>
int main()
// create an array with 5 entries all set to 10
// allocate size of transformed output array
// compute output vector as transform of tens
thrust::transform(tens.begin(), tens.end(), v.begin(), cusp::multiplies_value<int>(3));
// v = [30, 30, 30, 30, 30]
