can I am do shifting the number A(2,1) of matrix (A) ,one times in each iteration,('iter=0' ,iter=iter+1)? how can do that?
A=[1 2 3;4 5 6;7 8 9]
% Shift A(2,1)
for k=1:size(A,2)-1
A(2,:)=circshift(A(2,:),[0 1])
end

It shifts the entire second row one element at each iteration of the loop. Is that not what you wanted? Did you want to shift only the (2,1) element and not all of the elements in the second row? Either way, why? Seems like a funny thing to do unless it's homework or something. But it can't be homework because you would have tagged it as homework, so why do you want to do this?

Maybe you want to save all the results
clear
A=[1 2 3;4 5 6;7 8 9]
% Shift A(2,1)
for k=1:size(A,2)-1
A(2,:)=circshift(A(2,:),[0 1])
out{k}=A
end

size(array, n) means the length of array in the nth dimension. It DOES NOT mean array(n) which is the value of the array at index n. They're totally different things. By the way, you never answered my question in the comment at the very top.
