Hi there,
           I want to solve this problem which tells me form a
Similarity matrix based on input.
for eg if the input is ( 1 2 ),  (3 4 ), implying these are two groups
or cluster. I have to form the similarity matrix which looks
like 1 1 0 0
     1 1 0 0
     0 0 1 1
     0 0 1 1

I will appreciate anyone's suggestion for this logic

thanks
