MATLAB: Help with Reshaping Multidimensional Arrays

columnwiseindexingMATLABmultidimensional arraysreshape

I have Multidimensional Arrays, but I need of a reshaped matrix, indexing columns of each "dimension".
The number of arrays and number of rows can change according to the user, like that:
A (1:x, 1:3, 1:y) if x= 3 and y = 2
A(:,:,1)= [1 2 3 
           4 5 6
           7 8 9];
A(:,:,2)= [10 11 12
         13 13 15
          16 17 18];
Matlab answer 
B = Reshape (A,x*y,3)
B= [1 3  11
  4 6  13
  7 9  17
  2 10 12
  5 13 15
  8 16 18];
I need the answer:
B= [1  2  3
  4  5  6
  7  8  9
  10 11 12
  13 14 15
  16 17 18];
Thank for your help

reshape(permute(A,[1,3,2]),x*y,3)
