Generate data points and file from written program

t = linspace(0, 3, 200);
i = 6 * cos((2 * pi * t) -15);
v = 12 * sin((2 * pi * t) - 45);
plot(t, i);
hold on;
plot(t, v);
xlabel('t');
ylabel('v(t) & i(t)');
hold off;

Use this program to generate data points and file for plotting i(t) versus v(t)

‘Use this program to generate data points and file for plotting i(t) versus v(t)’

The instruction for the plot is clear:

figure
plot(v, i)
grid
xlabel('v(t)')
ylabel('i(t)')
axis equal

I have no idea what the file is supposed to contain. It could be the ‘v’ and ‘i’ data, the image file for the plot, or something else. See the relevant documentation on saving data and images to files.
