Hello, I am trying to wright a for loop that has two counters that run counter to each other.

here is one of my attempts limiting the size of .rows and .cols to 3 in reality those values will be much larger

 for (i = 1:3) 
    for(j = 3:-1:1)
                 handles.checkerDR{i}=...
                 handles.([handles.rows{i} handles.cols{j}]).String;
    end            
end

what I would like is checkerDR to be a cell array of

checkerDR{1}=handles.([handles.rows{1} handles.cols{3}).String;

checkerDR{2}=handles.([handles.rows{2} handles.cols{2}).String;

checkerDR{3}=handles.([handles.rows{3} handles.cols{1}).String;

so on and so forth does anyone have any ideas? i have been trying different iterations for a while and im not sure how to get this to work Thanks in advance

Rich - try using just one for loop

maxIter = 3;
for k=1:maxIter
    handles.checkerDR{k}=...
               handles.([handles.rows{k} handles.cols{maxIter - k + 1}]).String;        
end
