For instance v=(1,2,3) satisfices x^2 + y^2 + z^2 < 1?

You can use this condition
sum(v.^2) < 1
It will return either true or false

@John: What you have posted is valid code already:
(x-x_0)^2 + (y-y_0)^2 + (z-z_0)^2 < 1
All you have to do is to replace "x" by "v(1)", "y" by "v(2)" and the same for "z".
