cusp::less_equal_value< T > Struct Template Reference

Detailed description

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

less_equal_value is a function object that compares a given element with 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

less_equal_value is a function object. Specifically, it is an Adaptable Unary Function. If f(c) is an object of class less_equal_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 from 0 to 4
   cusp::counting_array<int> count(5);

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

   // compute output vector as transform of tens
   thrust::transform(count.begin(), count.end(), v.begin(), cusp::less_equal_value<int>(3));

   // v = [1, 1, 1, 1, 0]
   cusp::print(v);
}
