# Preventing all [x,y] figures appearing when running a plot of a circle

When plotting a circle using x=rcos(theta) and y=rsin(theta), I create a linspace to obtain many values for x and y and then plot [x,y]. However, whenever I run the function, all these values appear. How do I prevent this from happening? This is what top line looks like:
function [x,y] = disc_plot
Thank you

Adding semi column (;) for all instructions inside the function will prevent the printing of values.

I have no idea what you’re doing.
The correct syntax is:
r = 1;
theta = linspace(0, 2*pi);
x = r*cos(theta);
y = r*sin(theta);
plot(x,y)
grid % Optional
axis equal
