cusp::abs_functor< T > Struct Template Reference

Detailed description

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

abs_functor is a function object that computes the absolute value 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.
abs_functor is a function object. Specifically, it is an Adaptable Unary Function. If f(c) is an object of class abs_functor<T>, and x is an object of class T, then f(x) returns |x|.
#include <cusp/array1d.h>
#include <cusp/print.h>
int main()
// create an array with 5 entries from -2 to 2
// allocate size of transformed output array
// compute output vector as transform of tens
thrust::transform(count.begin(), count.end(), v.begin(), cusp::abs_functor<int>());
// v = [2, 1, 0, 1, 2]
