3.8 Vector Copies

Now let's deal with the problem opposite to Section 3.7. In other words, you have a view of another object's data, but you really want a unique copy. In this case, you can use the copy function. Here is a common situation within functions:

void foo(const RWMathArray<double>& v)
{
   RWMathArray<double> myCopy = v.copy();
   ...
   // Now you can play with myCopy's data while
   // honoring the const modifier of v...
}

In this example, myCopy and v each refer to their own data, and no aliasing takes place.
