You could just use plot3. Just remember to close the loop.
plot3([1,0,0,1], [0,1,0,0], [0,0,1,0])
If you want it filled in, you could use fill3.
figure
fill3([1,0,0], [0,1,0], [0,0,1],'m')

Same process. You just need a lot more points to make the shape look circular.
In 2D, you could use the rectangle function. See this example.
