Running an iterator "for" command in simulink?

Dear Guys.

I have a problem running Simulink. I want to Make a model and arrange in a way that after each run a new number enters the calculation process and get an individual output without overwriting the previous one.\My matlab command is simply like this:

for i=1:100

   for j=1:50

      x(i,j)=i+j

   end

end

this is a very simple command in matlab but in simulink if i use the intervals in constant block, the whole model runs together. how can i make such a model in simulink. Actually i want the model to do the j calculations and after that it goes and takes a new i and repeat the j calculation again and store the new sets of data as a new output without overwriting the previous one. By the way i think simulink will add all the outputs so instead of 5000 outputs we only have 1.

A copy of my simulink model has been attached.
