    %% Combine Line and Stem Plots
% This example shows how to combine a line plot and two stem plots. Then, it 
% shows how to add a title, axis labels, and a legend.
% 
% Create the data and plot a line.

x = linspace(0,2*pi,60);
a = sin(x);
b = cos(x);
plot(x,a+b)
%% 
% Add two stem plots to the axes. Prevent new plots from replacing existing 
% plots using |hold on|. 

hold on
stem(x,a)
stem(x,b)
hold off
%% 
% Add a title, axis labels, and a legend. Specify the legend descriptions 
% in the order that you create the plots.

title('Linear Combination of Two Functions')
xlabel('Time in \musecs')
ylabel('Magnitude')
legend('a+b','a = sin(x)','b = cos(x)')
