I have three smaller Matrices that I want to transform to one bigger one with the following order:

>> A1 =

` 1 1 2 2 3 3 4 4`

A2 =

` 5 5 6 6 7 7 8 8A3 = 9 9 10 10 11 11 12 12`

They should be transformed to one Matrix in this order:

B =

` 1 1 2 2 5 5 6 6 9 9 10 10 3 3 4 4 7 7 8 8 11 11 12 12`

So always take the first n-rows of each matrix (here n=2, in the actual case 'n' ist way higher), then take all the second "packages" and so on (In this case: Take first two lines of each Matrix, then take lines 3-4 of each matrix, then lines 5-6 of each matrix and so on)

Is there a nice and quick solution that does not require loops? Maybe using reshape or some functions to swap lines or using indices or so..?

Thanks in advance again!
