i am new to matllab, below is the given code, i tried to run it but i think i am missing something
t= 0:0.001:3;
xref = sin(2*pi*t).*cos(2*pi*t);
xs1 = 0.5*sin(2*pi*t).*cos(2*pi*t);
xs2 = 1.0*sin(2*pi*t).*cos(2*pi*t);
xs3 = 1.0*sin(2*pi*t).*cos(2*pi*t)+0.1*sin(2*pi*10*t);

Not really clear what the problem is. Do you want to regenerate the plot?
t= [0:0.001:3]'; % changed to column vector.
xref = sin(2*pi*t).*cos(2*pi*t);
xs1 = 0.5*sin(2*pi*t).*cos(2*pi*t);
xs2 = 1.0*sin(2*pi*t).*cos(2*pi*t);
xs3 = 1.0*sin(2*pi*t).*cos(2*pi*t)+0.1*sin(2*pi*10*t);
subplot(3,1,1);
plot(t,[xref, xs1])
subplot(3,1,2);
plot(t,[xref, xs2])
subplot(3,1,3);
plot(t,[xref, xs3])

figure;
subplot(3,1,1);
plot(t,[xref; xs1])
subplot(3,1,2);
plot(t,[xref; xs2])
subplot(3,1,3);
plot(t,[xref; xs3])
