cusp::conj_functor< T > Struct Template Reference

Detailed description

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

conj_functor is a function object that computes the conjugate of a given element.

Parameters
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.
Overview
conj_functor is a function object. Specifically, it is an Adaptable Unary Function. If f(c) is an object of class conj_functor<T>, and x is an object of class T, then f(x) returns |x|.
Example
#include <cusp/array1d.h>
#include <cusp/print.h>
int main()
{
// create an array with 5 entries from 0 to 5
cusp::counting_array< cusp::complex<float> > count(5, cusp::complex<float>(0,-2));
// allocate size of transformed output array
cusp::array1d<cusp::complex<float>,cusp::host_memory> v(5, 0);
// compute output vector as transform of tens
thrust::transform(count.begin(), count.end(), v.begin(), cusp::conj_functor< cusp::complex<float> >());
// v = [(0,2), (1,2), (2,2), (3,2), (4,2)]
}
