I want to run a for loop that allows me to find an a range of months and years and give me the cell number they are in. But when I used find(), it doesnt assign it to a variable so I lose the cell number its in every time the for loop runs. So far I have this:

 for i = 2009:2014
   for j = [1 4 12]
         tInd = find(y==i&m==j);
         tInd_min = min(tInd)
         tInd_max = max(tInd)
    end
end
N = 36;
for k=1:N
    for i = [2009 2010 2011 2012 2013 2014]
        for j = [1 4 12]
            my_field = strcat('v',num2str(k));
            tInd = find(y==i&m==j);
            tInd_min.(my_field) = min(tInd)
            tInd_max.(my_field) = max(tInd)
        end
    end
end

Where the first one finds every index and spits it out. The second for loop assigns names to the variables wrong. Thanks in advance!
