IMO, yes. I would also check v itself and add to the javadoc contract that IAE is thrown if v is null. This is not consistently done in [math], though, and rarely in the linear package, so I am OK just letting the NPE propagate if v is null. It is a little awkward that v itself being null leads to NPE, but a component of it null leads to MIAE.
