Why am I getting the error "Array indices must be positive integers or logical values."?

Error :

Hi,
You have overlooked .* after y:
kfinal=(x.*(u.*x-v.*y)-y.*(u.*y+v.*x))./(x.^2+y.^2)+a.^2.*(x.*(u.*x-v.*y)+y.*(u.*y+v.*x))./((u.*x-v.*y).^2+(u.*y+v.*x).^2);
nfinal=(x.*(u.*y+v.*x)+y.*(u.*x-v.*y))./(x.^2+y.^2)+a.^2.*(x.*(u.*x+v.*y)-y.*(u.*x+v.*y))./((u.*x-v.*y).^2+(u.*y+v.*x).^2);
