I suggest you read these two Mathworks' websites carefully:

It depends on the types of B, C and D, and the definition of "+" and "modulus" in your case. Is this group theory or are you talking of simple vectors? Is "+" the joining or the addition?
Without clean definitions of the data and operators asking for a conversion to Matlab is not meaningful. Example: How to program the BlöderNasenmann operator to Matlab when it is applied to Quabla Fabla? Although the meaning is clear to me, no reader can have a reliable idea what I'm talking of.

N=union (B,C)+abs(intersect(B,C)) Take a lot of care about matrix dimensions. The intersection matrix is smaller or equal in size as of the two input matrices. Similarly, the union matrix is bigger or equal in size as of the two input matrices. Zero pad or make necessary changes to accommodate size differences.
