Making Matrix Dimensions Equal

I have a matrix 5130 x 2 (5130 rows and 2 columns). A second matrix is 2150 x 2. How can I make this equal to 5130 x 2 without losing or adding information, for instance by adding or subtracting zeros?

A = ones(5130,2);
B = ones(2150,2);

BA = vertcat(B,zeros(abs(length(A)-length(B)),2));

How come that this does not count as adding information? :)
