MATLAB: Is there an equivalent function to the “kron(x,y)” that uses subtraction as its operation rather than multiplication

kron subtraction matrices

For example,
say we have two matrices as follows:
>> A = [1 2;3 4]
A =
       1     2
       3     4
>> B = [5 6;7 8]
B =
       5     6
       7     8
>> kron(A,B)
ans =
       5     6    10    12
       7     8    14    16
      15    18    20    24
      21    24    28    32
However I want a matrix that will subtract every component of matrix A by every component of matrix B, yielding a 4×4 matrix as follows:
A - B = 
  [-4 -5 -3 -4;-6 -7 -5 -6;-2 -3 -1 -2;-4 -5 -3 -4]
Note that I switched the multiplication function with subtraction BY HAND here. I need to do this with two 100×100 matrices, so it wouldn't be so easy. Thanks

Best Answer

A = [1 2;3 4]
B = [5 6;7 8]
C=cell2mat(arrayfun(@(x) x-B,A,'un',0))
