Storing vectors for different time steps in same variable name

I have a vector A of size 30 by 1, which changes its value for every time steps (ts). How will I store all the values in a same variable name say 'b' ? After storing I have to plot all its changes in single command. How can I do it ?

Why don't you use a matrix?

Let's say you have 10 timesteps (1 to 10),

 ts = 1:10;

so now you'll need to track A's changes during every timestep. So create a 30x11 matrix and the first column being A's initial values.

 A = zeros(30,11);

fill first column with initial values,

 A(:,1) = rand(30,1);

now do something which changes this first column during every timestep,

 for k=1:numel(ts)
   A(:,k+1) = rand*A(:,1); %or even A(:,k+1) = rand*A(:,k);
 end

now plot all changes,

plot(A)

you'll see 11 curves each for a timestep plus initial states.
