appending or padding zeros before a matrix in matlab

hello, if i have a matrix

             u = [1 0 1 1]
and i want to append zeros before it upto a length n:

             u1 = [0 0 0 0 0 0 0 1 0 1 1]

where n =7.

How should i? i tried this

             zeros(1,n) 
then tried to concatenate it with u but couldnt concatenate either.

regards.

Maybe you did not correctly concatenate them?

u=[1 0 1 1]
u1=[zeros(1,7) u]
