Cycle through arrays in for loop

I am trying to cycle through several array in a for loop. The for loop will plot each array and eventually make a animation (writeVideo). My arrays are named y0 through y500. How can I cycle through them such that I can access each array as for i =0:500, plot(x,y(i)).
