Multi-line Titles in LaTeX on Response Plots

So by combining several tips and tricks from past articles on this website, I have come up with the some code in an attempt to make multi-line titles of multiple step responses (subplots) in one figure with a variable that changes. All of this inside a for loop. Then I got stuck.
Basically what it boils down to: A regular plot can accept multiple-line titles but these response plots cannot. The following code will do what I need it to do:
plot(1:10)
title({'First line','Second line'})
However, this will not (where sys is a transfer function)
step(sys)
title({'First line','Second line'})
This throws errors:
??? Parameter must be a string.
Error in ==> ctrluis.axesgroup.addbypass>localTitle at 25
this.Title = string;
Error in ==> mwbypass at 18
hh = feval(fcn{:},varargin{:});
Error in ==> title at 38
h = mwbypass(ax,'MWBYPASS_title',string,pvpairs{:});
Error in ==> title at 23
h = title(gca,varargin{:});
For those who want to pursue what I am doing, here's all of my code:
format long
syms s;
t = 1:0.01:10;
omega_n = 2.47;
zeta = [0.4, 0.7, 1.0, 2.0];
for i = 1:length(zeta)
N = omega_n^2;
D = s^2 + 2*zeta(i)*omega_n*s + omega_n^2;
sys = simplify(expand(N/D));
[N, D] = numden(sys);
num = sym2poly(N);
den = sym2poly(D);
sys = tf(num, den);
subplot(2,2,i)
step(sys, t);
subtitle = cellstr(char(['\makebox[4in][c]{' 'Step Response of ' '$$G(s)$$}'],...
['\makebox[4in][c]{' '$$\omega_n=2.47$$' ' and ' '$$\zeta=' num2str(zeta(i)) '$$}']));
title(subtitle,...
'FontSize', 12,...
'interpreter', 'latex',...
'FontName', 'Times')
end

So trick MATLAB!
close all % So you know I am starting fresh
T = title({'First line','Second line'});
set(gca,'visible','off')
set(T,'visible','on')
step(sys) % Make your other plot here.
You can do most anything here, including just calling TEXT to make your title. A title is just a text object.

Perhaps you need to create another axes object for the STEP function to use. Do this after setting the title to visible. Or possibly set the handlevisibility of the invisible axes to off at the same time it is made invisible.

Have you tried this?
subtitle = ['\parbox[b]{2in}{\centering Step Response of ' '$$G(s),10,... '$$\omega_n=2.47$$' ' and ' '$$\zeta=' num2str(zeta(i)) '$$}'];
