clear; close all;

%*********************************************************
% Here's the first way -- just ask for multiple plots on the
% same plot line
%*********************************************************
x=0:.01:20;
y=sin(x);   % load y with sin(x)
y2=cos(x);  % load y2 with cos(x), the second function

% plot both

plot(x,y,'r-',x,y2,'b-')
title('First way')

%*********************************************************
% Here's the second way -- after the first plot tell Matlab
% to hold the plot so you can put a second one with it
%*********************************************************

figure
plot(x,y,'r-')
hold on
plot(x,y2,'b-')
title('Second way')
hold off
