Question

Here is the MATLAB code for the plot of a signal I created. This plot must contain more than one data cursors to show the periodicity. Please need help with how to include the data cursors to show the periodicity.

%MATLAB code

t=0:0.1:10*pi;

a=cos(3*t);

subplot(3,3,1);

plot(t,a)

xlabel('time');

ylabel('amplitude');

title('plot of cos(3*t)');

Answer 1

Execute the code:

%MATLAB code
t=0:0.1:10*pi;
a=cos(3*t);
subplot(3,3,1)
plot(t,a)
xlabel('time');
ylabel('amplitude');
title('plot of cos(3*t)');

Follow these steps.
