Matrix element changes according to reference

i have matrix Y and modify as ANS

Y=[ 11 12 13;

21 22 23;

31 32 33]

A=[1 1;

2 3;

3 2]

ANS=[ 11 13 12;

31 33 32;

21 23 22]

i have A matrix which indicates changes in matrix i.e., 1 is replace with 1, 2 is replace with 3 and 3 is replace with 2

according to that i want to change matrix Y to ANS. Change matrix elements using matrix A

Y=[ 11   12   13;
      21   22   23;
      31   32   33];
A=[1  1; 
     2  3; 
     3  2];

Y(A(:,2), A(:,2))

ans = 3×3

11 13 12 31 33 32 21 23 22
