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)?

n is below :

for n=1:5

A =[a b c; d e f; g h i];

end

Can you help me how to plot first row first column (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.

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,:));
