Stupid question ;)

Hi,
I have a simple question but I did not manage to find the solution. I am working on some block bootstrap resampling methods, and I need to take a vector x with some data and divide it into blocks and then resample these blocks.
Let me show you one on simple example
step 1 : I take x = [ 1:20 ] step 2 : I created a matlab function that give me these blocks from x; u =
1 4 7 10 13 16 2 5 8 11 14 17 3 6 9 12 15 18
step 3: I want now to create a vector or a matrix named B with B(1)=u(:,1) B(2)=u(:,2) B(3)=u(:,3) B(4)=u(:,4) B(5)=u(:,5) B(6)=u(:,6)
How to create B?
When I will have B, I will just create a lot of resamples with replacement of these blocks for example X = [ B(1) B(1) B(6) B(4) B(3) B(1)]
Thank you so much in advance,
