Hii,
I am trying to multiply two matrices defined as follows:
U = [1 1 1 1 0 0 0 0 0 1 1];
G = [0 1 0 1 1 0 0 0 0 0 0 0 0 0 0
0 0 1 1 0 1 0 0 0 0 0 0 0 0 0
0 1 1 0 0 0 1 0 0 0 0 0 0 0 0
0 1 1 1 0 0 0 1 0 0 0 0 0 0 0
1 0 0 1 0 0 0 0 1 0 0 0 0 0 0
1 0 1 0 0 0 0 0 0 1 0 0 0 0 0
1 0 1 1 0 0 0 0 0 0 1 0 0 0 0
1 1 0 0 0 0 0 0 0 0 0 1 0 0 0
1 1 0 1 0 0 0 0 0 0 0 0 1 0 0
1 1 1 0 0 0 0 0 0 0 0 0 0 1 0
1 1 1 1 0 0 0 0 0 0 0 0 0 0 1];
Here U is a matrix of size 1*11 whereas G is a matrix of size 11*15. I have no idea of how to do binary multiplication any suggestions in this regard??
Thanks for you help.

I tried using the "mod 2" and "logical" with some problems I am working on. I am not sure what you are referring to when you talk about the boolean addition being defined as an exclusive-or, but the "mod 2" gives the correct answer and "logical" does not

Onyekachi Ukeje-Eloagu: in your situation, should boolean 1+1 be equal to 1 ("or") or should it be equal to 0 ("exclusive or") ?
