How can I fix "Error using subsref, index exceeds matrix dimensions"?

I've wrote this code. The problem is there are 22 features in the dataset. But it's only generate Feature 1 and its shows the error below at the Command Window. Can you help me how to fix this problem so that all features can be generated successfully? Thank you.

training = csvread ('training.csv');
class = csvread ('class1.csv');

A = prdataset(training,class);
[instances,nvars] = getsize (A);

for i = 1:22
    B = [A(:,i) A.labels];
    C = B(:,1:2);
    [D I] = sort (C(:,1),'ascend');
    E = C(I,:);
    disp('feature=');disp(i);
    disp(E(:,1:2));
    original = 1;
    nonoriginal = 1;

      counter1=1;

      while(original<instances)
          nonoriginal = original+5;                                           %ideal cutpoint
          disp('nonoriginal=');disp(nonoriginal);
          truefalse = isequal(E.labels(nonoriginal),E.labels(nonoriginal+1));
          disp('truefalse=');disp(truefalse);

          if (truefalse == 0)                                                 %if different class
                   original = nonoriginal;
                   disp('original=');disp(original);
                   arr(counter1,i) = E(original,1);
                   counter1 = counter1+1;
          else 
              nonoriginal = nonoriginal+1;
              disp('nonoriginal=');disp(nonoriginal);
              yesno = isequal(E.labels(nonoriginal),E.labels(nonoriginal+1));     %if same class
              disp('yesno1=');disp(yesno);
                   while (yesno == 1)
                      nonoriginal = nonoriginal+1;
                      disp('nonoriginal=');disp(nonoriginal);
                      yesno = isequal(E.labels(nonoriginal),E.labels(nonoriginal+1));     %if same class
                      disp('yesno2=');disp(yesno);
                   end
                      original = nonoriginal;
                      disp('original=');disp(original);
                      arr(counter1,i) = E(original,1);
                      counter1 = counter1+1;
          end 

      end
  end

Error using subsref Index exceeds matrix dimensions.

Error in prdataset/subsref (line 18)

Error in Training (line 25) truefalse = isequal(E.labels(nonoriginal),E.labels(nonoriginal+1));
