For loop stops in the first find

Why does this for loop stop at the first find?.

    Val  = max(max(D(:, 2:end), [], 2));
    rows = [];
    for i = 1:size(D, 1)
       if (any(D(i, 2:end) == Val))
          rows = [rows, i];
          D(rows)
       end
    end

    D(rows)

should be

    D(rows, :)

@Walter Roberson in case I'm looking to turn the value in index i would it still work?

[Image Analyst]

What are you trying to store for each row - the max value or all the indexes where it occurs? Or both?

[Fil Okua]

@Image Analyst, I am trying store both.

[Fil Okua]

But I'm only interested in the values at the indexes

    Val  = max(max(D(:, 2:end), [], 2));
    rows = [];
    for i = 1:size(D, 1)
       if (any(D(i, 2:end) == Val))
          rows = [rows; D(i,:)];
       end
    end

However...

    mask = any(D == max(max(D(:,2:end))),2);
    rows = D(mask,:);

with no loop is all that is needed.
