% 3.12	Given the array A defined as:
% 			A = [1 3 2; 2 1 1; 3 2 3];
% which of the following commands will produce this array?

% a.   	B = [A(3,2:3) ; A(2,1:2)];
% b.  	B = [A(3,1:2) ; A(2,1:2)];
% c. 	B = [A(1,2:3) ; A(1:2,3)’];
% d. 	B = [A(3,3:-1:2) ; A(2,2:-1:1)];

disp('b and c produce the given array.')
