MATLAB: Modify a plot in a for loop

for loopplot

I would like to know if it is possible to modifidy all the curve generated by this for loop. For example to add a distintive marker for each one of the curves.
omega = 0:0.01:3;
for zeta = [0 0.15 0.5 1 2]
mu = 1./(sqrt((1-omega.^2).^2+4*zeta^2*omega.^2));
p = plot(omega,mu);
hold on
end
p.Marker = '*';
p.MarkerIndices = 1:7:length(omega);
With this code, Matlab only apply the changes to the last curve plotted.

The idea is to collect all of the line object handles.
I've also restructured your code; see the inline comments for details. 
omega = 0:0.01:3;
zeta = [0 0.15 0.5 1 2];    % Defined outside of the loop
p = gobjects(5,1);          % pre-allocate, one for each zeta
hold on                     % move this out of the loop
for i = 1:numel(zeta)       % Loop over integer values starting with 1
    mu = 1./(sqrt((1-omega.^2).^2+4*zeta(i)^2*omega.^2)); % note zeta(i)
    p(i) = plot(omega,mu);  % store all handles
end
set(p, 'Marker',  '*');     % set marker for all handles in p
set(p, 'MarkerIndices', 1:7:length(omega)); % set MarkerIndices for all p
