How do I rearrange a matrix in a loop

I want to change the order of each element in a matrix.

For example I need to transform matrix A into matrix B using a For loop.

A =

   10    5
    4   10
    2    3
 
B =

   10    5    0    0    0    0
    0    0    4   10    0    0
    0    0    0    0    2    3
   10    0    4    0    2    0
    0    5    0   10    0    3

No loops needed:

a = num2cell(A,2);
B = blkdiag(a{:})
