Create a new matrix with the for loop

w_u = zeros(361,361,252);
w_v = zeros(361,361,252);
ind = 10:16;
for t = 1:length(nu1) %nu1 and nv1 are 361*361*436 in size
  if t <=36
    %the months required in the analysis are 252
    w_u = nu1(1:361,1:361,ind);

*Here is the problem, i understand every time the loop iterates it creates a matrix of the size 361*361*7. I am not sure how to save this matrix and keep adding on to the same matrix until i have the required matrix of the size 361*361*252*

      tu(:,:,t:t+6) = w_u; 
      w_v = nv1(1:361,1:361,ind);
      tv(:,:,t+6) = w_v;
      %         end
      ind = ind+12;
    else
    end
  end

Can you explain the question again with different example?

If (big if) i interpreted your code right you are trying to do something like this:

w_u = zeros(361,361,252);
w_v = zeros(361,361,252);
ind=10:16;
for t= 1:36 %252/7=36
    idx =(t-1)*12+ind;
    w_u(:,:,(t-1)*7+(1:7)) = nu1(:,:,idx);
    w_v(:,:,(t-1)*7+(1:7)) = nv1(:,:,idx);
end

@Dennis: you should put that as an answer.

@Dennis: Yes, you interpreted it correctly. and Thank you,that's the right answer. Can you post it as answer so i can accept this

end

Glad i could help :)
