% EXAMPLE 1 2D Plots and Subplots

% A. LOAD DATA

% Load data from file response.dat using Import Wizard
% Hint: use Create Vectors from Columns option. 
% Use WHO to confirm you have created vectors T, YI, and YO.

% B. PLOTTING

% B1. Create a figure with two subplots one above each other. 
% Plot the input YI and the response YO vs. time T on the top subplot
% (use different colors and/or markers). Add figure title and subplot legend.

subplot(211)
plot(T, YI);
hold on
plot(T, YO, 'r-');
hold off
legend('INPUT', 'RESPONSE')
title('AMPLITUDE AND PHASE CHANGE')

% B2. In the second subplot, graphically determine the changes in
% amplitude and phase. 
% Hint: Plot the same figure as above, then change the x-axis range using
% the Property Editor.

subplot(212)
plot(T, YI)
hold on
plot(T, YO, 'rx')
hold off
