MATLAB: “Scaling” a matrix of matrices into a supermatrix

MATLABmatrix manipulation

Is there a simple command for repeating matrix-like elements within a matrix without using a loop? For example, say I have a matrix such as
>> A = [1,2,5,6;3,4,7,8;9,10,13,14;11,12,15,16]
A =
     1     2     5     6
     3     4     7     8
     9    10    13    14
    11    12    15    16
I want to scale this matrix, such that it becomes
>> B = [1,2,1,2,5,6,5,6;3,4,3,4,7,8,7,8;1,2,1,2,5,6,5,6;3,4,3,4,7,8,7,8;9,10,9,10,13,14,13,14;11,12,11,12,15,16,15,16;9,10,9,10,13,14,13,14;11,12,11,12,15,16,15,16]
B =
     1     2     1     2     5     6     5     6
     3     4     3     4     7     8     7     8
     1     2     1     2     5     6     5     6
     3     4     3     4     7     8     7     8
     9    10     9    10    13    14    13    14
    11    12    11    12    15    16    15    16
     9    10     9    10    13    14    13    14
    11    12    11    12    15    16    15    16
I'm simply looking for a command or a combination of such to create this matrix.

easy solution: 
A=[1,2,5,6;3,4,7,8;9,10,13,14;11,12,15,16]
B=cell2mat(repelem( mat2cell(A,[2 2],[2 2]),2,2))
