make matrix for given vector ( better method)

for given vector x = [x1 x2 x3 x4 x5]

I want to make square matrix y = [x; x; x; x; x]

actually I can make it using

--------------------

 for i = 1 : 5

    y(i,:) = x

 end

--------------------

but i have to do such calculation many times, so I want even fast method!

Please help me!!

If x is a column vector:

Y=repmat(x,1,size(x,1));

If x is a row vector:

Y=repmat(x,size(x,2),1);
