Using discrete time in Simulink

Hi,

i wanna to simulate this equation:

A_(l,j) (nT) = A_(l,j)(0T) + (2*pi*n)/ N where T = 2*pi/N and n = 1,2,...,N and l = 1,2,..., L and j = 1,2,..., K

My problem is, to use n, j and l. How can simulate with simulink such that model that it compute for all n, j and l ????

THX
