First, I have multidimensional data that look like
0 1
0 2
1 1
1 2
0 2
Second, I want to create a frequency table that counts the frequency of each row such as
0 1 1
0 2 2
1 1 1
1 2 1
where the third column counts the number of occurances of each two-dimensional row.
Third, I looked at tabluate function at
But it seems that the tabulate function only looks at the one-dimensional data.
Then, how can one create a frequency table for such multidimensional data?

[u, ~, c] = unique(data, 'rows', 'stable');
Wanted = [u, accumarray(c, 1)]
