3.7 Function reference()

Let us say you have an old variable and you want to re-initialize it to view some other data. For this task, you can use the member function reference():

#include <rw/math/mathvec.h>
main()
{   
   RWMathVec<double> a, b, c;
   .
   .
   .
   a.reference(b + c);
}

This produces exactly the same results as:

#include <rw/math/mathvec.h>
main()
{
   RWMathVec<double> b, c;
   .
   .
   .
   RWMathVec<double> a = b + c;
}
