Say there is a input square matrix: A
And we create a identity matrix of the same order as A and name it B
Then we create a augmented matrix Ag = [A, B]
now I perform some operation on the Ag matrix and now I want to print the changed B matrix within the Ag matrix. How can I do that?

n = 5 ;
A = rand(n) ; % square matrix
B = eye(size(A)) ; % Identity matrix
Ag = [A B] ; % augemented matrix
