We prove a general Tura n Kubilius inequality and use it to derive that the number {(S) of divisors of an integer r\_r matrix S verifies {(S)=(Log |S|) Log 2+o(1) for all but o(X) matrices of determinant X. This is in sharp contrast with the average order which is Ä |S| ; r &1 (Log |S|) # r for ; r
