Converting 2D array to 3D array by sector

Hi all,

I have a question concerning reshaping a 2D array into a 3D array, where each 2D array is arranged by a block of rows and columns from the original.

Say I have an array 'aa'

'aa' is comprised of a number of blocks of data = x, with a number of rows = n, and number of columns = m

For example if

x = 2

n = 2

m = 3

aa = randi(1000,x*n,m);

Can anyone show me how to reshape 'aa' into a destination array 'bb' to be organized as follows

bb(:,:,1) = aa(1:n,:);

bb(:,:,2) = aa(n+1:2*n,:);

The same pattern repeats for the full size of my problem (x = 30 , n = 440, m =320)

I am trying to avoid loops as the number of blocks of data 'x' is likely to increase down the road.

Thank you in advance for any help that you may provide.

 bb = reshape(aa.', 1, [], size(aa,2))

This is exactly what I was looking for, thank you very much.
