Question

A. We continue our exploration of MATLAB's plotting facilities by considering plots with left and right y axes. Such plots are particularly appropriate when we want two plot curves with different scales. We are given three functions to be plotted: fit) sin(rt) g(t)= 20Vt . f2(t) = cos(2nt) . e-t Submit a MATLAB script that produces the plot of Figure The key command whose documentation you want to read is yyaxis. This is a relatively new com mand. In the past this type of plots was obtained with the now-obsolescent plotyy

Explanation / Answer

% create vecto for time

t = [ 0 : 0.01 : 10 ];

% vector to store f1(t)

f1 = [ 1 : length(t) ];

% vector to store f2(t)

f2 = [ 1 : length(t) ];

% vector to store g(t)

g = [ 1 : length(t) ];

for i = 1 : length(t)

   

   f1(i) = sin( pi * t(i) );

  

   f2(i) = cos( 2 * pi * t(i) ) * exp( -t(i) );

  

   g(i) = 20 * sqrt( t(i) );

   

end

yyaxis left

% set title

title('Dual-axis plot');

ylabel('f1(t).f2(t)');

xlabel('t');

hold

% plot the graph

plot( t , f1 , 'b' , t , f2 , '--');

% for right y axis

yyaxis right

% set y label

ylabel('g(t)');

hold

% plot the graph

plot( t , g , 'r');
