Here's a vector-subtract graph that should do what Ed wants, might need 
some tweaking.

Performance won't be as good as with a dedicated block to do the same 
thing, but if the data rates aren't obscene, this should
  work reasonably well, I think.  Ed mentioned that the vector is the 
result of an FFT, so I simply placed an FFT block in there for
  illustrative purposes.
