Ricardo !!!

Please test the code.
This code does exactly as you ask.
It will return 1's for all that are the same and
return 0's for all that are different.

The logic is

2Dseq = {{1,2},{3,4}} - {{1,1},{6,4}}
--2Dseq now equals {{0,1},{-3,0}}
2Dseq = not 2Dseq
--2Dseq now equals {{1,0},{0,1}}

I did not create this routine BUT
That is how I would have done it my self.

ENJOY.
