Permutation and combination

Hi all, I am trying to solve a problem. I need a matlab code which automatically calculates the possible number of combinations of dividing a number or constant to eg 3 objects using a defined step.

eg to divide 60 to A, B, C using step size 60. Possibilities will be [60 0 0; 0 60 0; 0 0 60] --> 3 possible combinations

120 using step 60, will be [120 0 0; 0 120 0; 0 0 120; 60 60 0; 60 0 60; 0 60 60] --> 6 possible combinations ... and so on

Can anyone help me with a matlab code which computes these possible number of combinations? I will be very grateful. Hummy
