In this problem, the author is imagining again an abstract pyramid made by layers of square matrices of zeros that decrease evenly until the top is reached (the top is made by ones; for instance, a pyramid of base 5(n) would be zeros(5)-> zeros(3) -> ones(1)). We are looking at the pyramid from the top view (that's why is flattened).
