How to plot from matrix

If I have matrix that the value change for every iteration by n, Ex : A=[a b c; d e f; g h i]
How can I plot the value of first row first column which is (a) vs n. (a) in y axes and n in x axes. And then I also want to plot second row second column which is (e) vs n in the same graph.

How are you storing the matrix during each iteration? Did you create a thrid dimension?
for k=1:100
A(:,:,k)=[a b c; d e f; g h i];
end
If so, after completing your loop you could easily plot your desired data:
plot(n,A(1,1,:),n,A(2,2,:));%not sure what n is (n=1:100)?

You need to do something like:
for n=1:5
A(:,:,n) =[a b c; d e f; g h i];%assuming a,b,c,d,e,f,g,h,i are changing each iteration
end
n=1:5;
plot(n,A(1,1,:),n,A(2,2,:));
