For loop confusion!

Question

0 个投票

ind1 = 1:6;
for t2=1:size(mm_r,3);
    if t2 <= 6
        wt_r = mm_r(1:361,1:361,ind1);
        wint2_r(:,:,t2) = mean(wt_r,3); %wint2_r is of 361*361*6
          ind1 = ind1+6;
      else
      end      
  end

To calculate the sequential differences I want to write this part in for loop, but it is not working out the way i want lets say an_r of size 361*361*5

anom_90_84_r = wint2_r(:,:,2) - wint2_r(:,:,1);
anom_96_90_r = wint2_r(:,:,3) - wint2_r(:,:,2);
anom_02_96_r = wint2_r(:,:,4) - wint2_r(:,:,3);
anom_08_02_r = wint2_r(:,:,5) - wint2_r(:,:,4);
anom_15_08_r = wint2_r(:,:,6) - wint2_r(:,:,5);

Don't know that we can help simply on the basis of "it isn't working the way I want", sorry. What is the desired output from what input? Generally a (very small) sample case that illustrates numerically helps clarify what often is difficult describing solely in words.

Just letting you know that you didn't really need the if statement if you just start the for loop at 2.

for k = 2:size(wint2_r,3)
        anom_r = wint2_r(:,:,k)-wint2_r(:,:,(k-1));
        an_r(:,:,k-1) = anom_r;
end

Basically, are you asking how to dynamically name variable to store data. So in the for loop you would do this

anom_90_84_r = wint2_r(:,:,2) - wint2_r(:,:,1);
anom_96_90_r = wint2_r(:,:,3) - wint2_r(:,:,2);
anom_02_96_r = wint2_r(:,:,4) - wint2_r(:,:,3);
anom_08_02_r = wint2_r(:,:,5) - wint2_r(:,:,4);
anom_15_08_r = wint2_r(:,:,6) - wint2_r(:,:,5);
