Two vectors to matrix sorted on occurrence

I have a (n x 2) array, with labels in the first column and the hour they occur at in the second column. Labels are for ease of use given as 1, 2, 3, 4, ... and time is given as 1, 2, ..., 24.
So basically every label has a timestamp at the moment, most occur at many different times. Now I would like to create a matrix with labels as rows and number of times they occur at each hour in the colums. I cannot remember what this is called...
E.g. say that I have 6 hours and 5 labels, I want it to look something like this:
x = [2 0 0 1 0 2;
1 0 0 0 2 0;
0 0 0 0 0 0;
2 0 0 0 0 0;
1 2 4 5 6 0]
So label one occurred twice during the hour 1.
