How do I make a circle move within the specified axes so that it bounces off of the axes?

%How do I make a circle move within the specified axes so that it bounces off of the axes? It was suggested to just %use if statements to flip dx and dy from positive to negative or vice versa, however, I'm not sure how to even get %the circle moving on the plot.

r = 1; theta = 0:1:360; x = r*cosd(theta); y = r*sind(theta); plot(x,y);

Hi,

You could use a for loop to create a moving circle. Depending upon your use case, you will have to change some parameter in the equation of the circle in each iteration to create the moving effect, for example, change center, radius etc.The following link has an example which might be helpful for you.
