How can I draw a circle in matlab using parametric ecuations or the circle ecuation?

I'm new to matlab and I wanted to know

Answer 1

>> t=-pi:0.01:pi;
>> y=sin(t);
>> x=cos(t);
>> plot(x,y)

Answer 2

That's one simple way you can do it

x= sin(0:.01:2*pi);
y= cos(0:.01:2*pi);
plot(x,y);
axis equal

also try below, but you probably gonna get some warnings! lol

f=@(x,y) x^2+y^2-25
ezplot(f)
axis equal

Good Luck!
