How to create this "bean shape" in MatLab please?

Please see the attached screenshot for reference (the shape does not have to be exactly the same as the screenshot)

I am trying to create this shape, or a similar "bean" shape in MatLab. Thank you for your help.

If you are just getting started with Matlab, I would highly recommend that you take a couple of hours to go through the free online tutorial: Matlab Onramp

What have you tried so far?

Try this:

t = linspace(0, 2*pi, 1000);
x = 3 + 2 * sin(t) + cos(2 * t);
y = 4 * cos(t) - sin(2*t);
plot(x, y, 'b-', 'LineWidth', 2)
grid on;
xlabel('x');
ylabel('y');
axis equal
xlim([-.25, 5]);
ylim([-5, 5]);

Awesome! Thank you for the help.

Most of my MatLab models use the "surf" and "fsurf" functions, so that is what I am more comfortable with.

I see that you used the "plot" function, so thank you for showing me this alternative method.

Follow-up question: Is there any way to add a z-dimension to your "plot" function? From what I learned, perhaps "plot3" would be the one to use. Thank you.

You can use plot3 if you have some z value for each "t" value.
