How to generate an array based on the values of another array?

%Assign values ex: 2 becomes 4, 1 becomes 3, 3 becomes 2.....

A=[2 4;

1 3;

3 2;

4 1 ]

%Replace the new mappings at each position in the following array...ex:

B=[1 3;

3 1;

2 4;

4 3 ]

%New array generated C:

C=[3 2;

2 3;

4 1;

1 2 ]

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

A = 4×2

1 3 3 1 2 4 4 3

B=A;
A(B==2)=4;
A(B==1)=3;
A(B==3)=2;
A(B==4)=1;
A

A = 4×2

3 2 2 3 4 1 1 2
