Hi

I have got the following. But it does not do what I what:

for f=1:4
    for S=[3,4,7,11]
        Pf1(:,S)=Pf1BM1.allocation(:,f);
        Pf2(:,S)=Pf2BM1.allocation(:,f); % after this line (first iteration:f=1 and S=3), I would like that matlab goes to the second interation (f=2 and S=4) directly. 
        % So that the data in Pf1BM1.allocation(:,2) goes to Pf1(:,4) and Pf2(:,4). And in the third iteration (f=3 and S=7) the data in Pf1BM1.allocation(:,3) goes to Pf1(:,4) and Pf2(:,7)...     
end

In VBA I just would insert the code "go to f=1:4" after the line of code Pf2(:,S)=Pf2BM1.allocation(:,f);

Do you know any other alternatives?

Yeah, write your wanted input and allocation-arrays for a couple of steps. Something like:

f = [1 2 3 4];
S_from_f = {[1],[2,3],[3,7],[4,5,6]};
to_S     = {[2],[3,4],[4,9],[5,6,12]};
for i1 = 1:numel(f),
    for i2 = 1:numel(S_from_f{i1})
        Pf1(:,to_S{i1}(i2))=Pf1BM1.allocation(:,S_from_f{i1}(i2));
        etc...
    end
end
