MATLAB: Reshape matrix in the desired form

3d matrixreshape

Hi all,
My problem is that I would like to reshape a specific matrix in the form that I desire for my calculations, however I don't seem to be able to get it exactly as I want. Here is the specific example to my problem:
I have the following code:
 a = [1 2 3 4] ;
 b = [5 6 7 8] ;
 [x, y] = meshgrid(a,b) ;
 A = x ;
 A(:,:,2) = y ;
The above gives me an output as I desire, in the following form:
 A(:,:,1) =
     1     2     3     4
     1     2     3     4
     1     2     3     4
     1     2     3     4
 A(:,:,2) =
     5     5     5     5
     6     6     6     6
     7     7     7     7
     8     8     8     8
At this point, I would like to create another matrix called B, based on A, such that:
 B = [1 2 3 4 1 2 3 4 1 2 3 4 1 2 3 4 
      5 5 5 5 6 6 6 6 7 7 7 7 8 8 8 8] ;
I have tried using reshape to accomplish the above however I cant get this output from it.
Your help would be appreciated,
KR,
KMT.

B=[reshape(A(:,:,1)',1,16);reshape(A(:,:,2)',1,16)]
