Hi， I have

a=[1 2; 3 4; 5 6];

for m=1:4

    if m<=2
        b=a([2 3],:)
    else 
        c=a([1 2],:)
    end

end

I want to keep the answer for every loop, for example, I want to know the ouptut when m=1, m=2, m=3 and m=4 respectively. How am i going to do this?

Thanks.

Replace mynum with the index you're interested in:

result{mynum}

e.g., result{3} will give you the result for m=3
