I am doing my research. I have problem to make code to present this following matrices.

A=[ 1 2 3 4;
    3 2 1 4]

And i have this following matrices to present value in matrices A.

value=1, 
A(1)=[1 1 1;
      1 1 1]
value=2,
A(2)=[2 2 2;
      2 2 2]
value=3,
A(3)=[3 3 3;
      4 4 4]
value=4,
A(4)=[4 4 4;
      3 3 3]

So that I will get this following matrices

Res=[1 1 1 2 2 2 3 3 3 4 4 4;
     1 1 1 2 2 2 4 4 4 3 3 3;
       3 3 3 2 2 2 1 1 1 4 4 4;
       4 4 4 2 2 2 1 1 1 3 3 3]

Thanks for your help.

A = [1 2 3 4;3 2 1 4]
B{1} = [1 1 1;1 1 1];
B{2} = [2 2 2;2 2 2];
B{3} = [3 3 3;4 4 4];
B{4} = [4 4 4;3 3 3];
Res = cell2mat(B(A))

I see, you want the A as the indices to construct Res. I've updated the answer.
