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;

Examples

 #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.

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.
