template <class From, class To>
class RWConvertMathVec;

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

#include <rw/math/mathvec.h>

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
  function RWMathVec<double> s = RWConvertMathVec<int,double>(d);
            s = sin(s);
}

RWConvertMathVec<From,To>(const RWMathVec<From>& M);

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.

operator RWMathVec<To>(); 

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.
