Hi,

my code is mentioned below. The question is green after % if statement. May you help me?

function NewRanks=createRebRankings(f_Ranks,RebRanks,RebIndi)
nDates=size(f_Ranks,1);
nRebDates=size(RebRanks,1);
nRebIndi=length(RebIndi);
nFactors=size(f_Ranks(1,1,:),3);
nInstr=size(f_Ranks(1,:,1),2);
NewRanks=NaN(nDates,nInstr,nFactors);
for f=1:nFactors
    
    NewRanks(1,:,f)=f_Ranks(1,:,f);
    
        for d=2:nDates
            for i=2:nRebIndi
                if RebIndi(i)==0
                NewRanks(d,:,f)=NewRanks(d-1,:,f);
                else
                    for n=2:nRebDates
                    NewRanks(d,:,f)=RebRanks(n,:,f);
                    end %nRebDates
                end % if statement  --> After the excecution of the if statement I would like matlab to jump to d=2:nDates instead to i=2:nRebIndi.
            end % nRebIndi
        end % nDates
 end % nFactors

I have difficulty in understanding your question try "continue" instead of "break".

If I add "break" to my code. Then matlab jumps to the loop interation d=2:nDates. Thats good. But it is only the half solution. What I am looking for: After jumping back to d=2:nDates I want that i=2:nRebIndi continues to the next Itereation.

In other words:

the first loop iteration for nDates is 2 (as it begins by 2) and for the nRebIndi is 2 as well. After those first Interations (if I insert break), matlab jumps to the next iteration. Which is nDates 3 BUT nRebIndi iteration stays frozen at 2 (because of brerak) instead also showing 3

Thanks for your answer.

The thing is that with "break" matlab jumps to d=2:nDates which is what I want. However, the loop i=2:nRebIndi stays frozen/terminates. And I want this loop (Iteration) to continue after getting to d=2:nDates.
