Detailed Description

template<class From, class To>
struct RWConvertMathVec< From, To >

Class RWConvertMathVec<From,To> converts between RWMathVec types with different datatypes.

Synopsis

template <class From, class To>
class RWConvertMathVec;

Example

#include <rw/math/mathvec.h>

int main()
{
       // create a length 5 vector of 1's
  RWMathVec<int> d(5,1);

       // convert int vector d to a DComplex
       // vector c with all real parts 1
  RWMathVec<DComplex> c = RWConvertMathVec<int,DComplex>(d);

       // convert int vector d to a double vector
       //and then call sin
  RWMathVec<double> s = RWConvertMathVec<int,double>(d);
  s = sin(s);
}

Constructor & Destructor Documentation

template<class From, class To>

RWConvertMathVec< From, To >::RWConvertMathVec ( const RWMathVec< From > &  v )

inline

Constructs a new vector of type RWMathVec<To> that can be used anywhere as a type RWMathVec<To> . Note that a temporary array is created every time this constructor is invoked, but the conversion operator below can be used repeatedly without creating additional temporaries.

Member Function Documentation

template<class From, class To>

RWConvertMathVec< From, To >::operator RWMathVec< To > ( )

inline

Automatic conversion operator that enables class RWConvertMathVec<From,To> to be used as an RWMathVec<To> . While the actual conversion takes place in the constructor, this operator provides a reference to that converted vector.
