for k = 1:length(x)-1
    xstep = x(k+1)-x(k);
    xMove(obj, xstep)
    ystep = y(k+1)-y(k);
    yMove(obj, ystep)
    redraw
end

You have to modify the code of bounceFunc to accept arrays for all inputs:

function bounce = bounceFunc(obj, addx,addy,x,y)
    n = numel(obj);  % Number of objects
    
    %CREATE A FUNCTION OF THIS SO THAT YOU CAN REUSE IT FOR MULTIPLE BALLS
    while all((x >=0 & x <= 500) & (y >= 0 & y <= 500))
        for k = 1:n
          [x y] = getCenter(obj(k));  % You overwrite the inputs x and y here?!
          if y >= 480
              addy(k) = -addy(k)
          end
          if y <= 20
              addy(k) = -addy(k)
          end
          if x >= 480
              addx(k) = -addx(k)
          end
          if x <= 20
              addx(k) = -addx(k)
          end
          xMove(obj(k),addx(k)) 
          yMove(obj(k),addy(k)) 
        end
    redraw
    end
end

Now create the balls before calling the bounceFunc equivalently:

obj(1)       = drawBall(xc, yc, rad, col)
[x(1), y(1)] = getCenter(obj(1))
...
obj(2)       = drawBall(xc, yc, rad, col)
[x(2), y(2)] = getCenter(obj(2))
etc.

MATLAB: Help Nested Foor Loop

nx = numel(x);
ny = numel(y);
nxy = nx*ny;
xys = [nx, ny];
visit_order = randperm(nxy);
for k  = 1 : nxy
   [k1, k2] = ind2sub(visit_order(k));
   ZaberMoveAbsolute(zaber, Yaxis, y(k2));
   ZaberMoveAbsolute(zaber, Yaxis, y(k2));
   pause(2.0);
end

This visits all of the nodes in a random order.
