Making two matrices have the same size

I have the following two matrices, with the following sizes:

A: 71x1

B: 14x14

How can I make them both of size

14x14?

Can we use some sort of padding with zeros for instance?

How can we go about that?

Thanks.

How you do it depends on what direction you want the 71 pixels to go (before they run out): down or across.

A=rand(71,1) % Example
A=reshape([A;zeros(14*14-71,1)],14,14)
