If you want to pre-allocate just set your matrix to
A=zeros(n,m)
nxm is the biggest dimension you are expecting

Just working with a matrix in a normal way and using instructions that expand its size (ignoring the warnings you get) is the equivalent of creating a matrix of unknown size, but Azzi's solution above is usually preferable is you can put bounds on your "unexpectations"
