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.

Parameters

T	is 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.

Overview

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.

Example

#include <cusp/array1d.h>
#include <cusp/functional.h>
#include <cusp/print.h>

int main()
{
   // create an array with 5 entries all set to 10
   cusp::constant_array<int> tens(5, 10);

   // allocate size of transformed output array
   cusp::array1d<int,cusp::host_memory> v(5, 0);

   // 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]
   cusp::print(v);
}
