The error description is pretty clear, on the left hand side you have something you cannot assign a value to. The left hand side must be operator-free, so, the power operator is the problem here. If you want the third power of rSV to be equal to the right hand side, you need to take the third root of the equation, thus,
rSV= (y(1)^(2)+y(2)^(2)+y(3)^(2))^(1/2);
