Counting occurrence of elements in an array

How would I go about counting the occurrence of elements in an array including elements that may not be in the array.
For example if x = [2 3 2 4 5 6 8 2 9 5], I would like to produce an array that has the frequency of each element from 1 to 10 so it'd be output = [0 3 1 1 2 1 0 1 1 0]
Thanks

Use the hist function:
x = [2 3 2 4 5 6 8 2 9 5];
binc = [1:10];
counts = hist(x,binc);
result = [binc; counts]
produces:
result =
1 2 3 4 5 6 7 8 9 10
0 3 1 1 2 1 0 1 1 0
