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

then the third element in the created array will be the maximum in the next 13 number and fourth is the largest in the next 14 numbers and so on

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');
