Subtract a signal form its delayed one

Hi all,

Say I have a signal "A" with a period of "T" seconds.

I want to sample this with a period of "T" staring at "T/2"    -> [T/2 3T/2 5T/2 ....]

and for the second signal, I want to sample with the same period of "T" but starting at "3T/2"  (basically a delay of T) ->  [3T/2 5T/2 7T/2 ....]

When I subtract these two signal I was expecting a vector subtraction (basically each column subtracted). However, that is not the case and the sampled values are subtracted based on the time they were sampled. 

My question is that how can I do vector/Matrix subtraction in Cadence? 

Thanks
