How to rearrange 3 small matrices to a bigger one with a certain order of rows without using loops

I guess this one is quite simple but yet I didn't come up with a nice solution:

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

>> A1 =

     1     1
     2     2

A2 =

     3     3
     4     4
A3 =

     5     5
     6     6

They should be transformed to one Matrix in this order:

B =

     1     1
     3     3
     5     5
     2     2
     4     4
     6     6

So always take the first row of each matrix, then take all the second ones and so on!

Is there a nice and quick solution that does not require loops?

Thanks in advance again!

   B=reshape([A1(:)' ;A2(:)'; A3(:)'],size(A1,1)*3,size(A1,2))

perfect, thanks!
