How are you supposed to divide a 2000 numbers array by 13, 14 and then what?

Try this:
numElements = 154*13;
data = rand(numElements, 1); % random numbers from 0 to 1
data2D = reshape(data, 13, [])'
theLargest = max(data2D, [], 2);
plot(theLargest, 'b.-', 'LineWidth', 2);
grid on;
xlabel('Set of 13');
Do you rather need to alternate 13, 14, 13, 14, 13, 14, etc.?

Looks like you figured it out since you've accepted Madhan's answer, so I won't spend my time on it.
