The properties: Vector x and Vector y are not defined in the VectorView Class

//Use two vectors to construct a vector view:
 kst> a=new Array();
kst> for(var i=0;i<100;i++){a.push(i)};
100
kst> x=new Vector(a)
Vector
kst> y=new Vector(a);
Vector
kst> v=new VectorView(x,y)
VectorView

//get the x vector of v
kst> v.x
undefined

//get the y vector of v
kst> v.y
undefined

v.x and v.y are not defined and therefore can not be used.
e.g
kst> v.x.length
Error: TypeError: Undefined value
