I have this data (Click Here)
I'd like to count how many links a first column number is to a second column number, and so on. For example, how many times the number 1da first column has the number 1 in the second column?

maxdata = max(max(Yourdata(:,1:2)));
counts = accumarray(YourData(:,1:2), 1, [maxdata, maxdata]);
Now counts(J,K) is the number of times the number J appeared in the first column with K in the second column of the same row.
