    %% Modify Polar Axes Properties
% Create a new figure with polar axes and assign the polar axes object to
% |pax|. Add a plot to the axes. Then, use |pax| to modify axes properties.
 
figure
pax = polaraxes;
theta = 0:0.01:2*pi;
rho = sin(2*theta).*cos(2*theta);
polarplot(theta,rho)

pax.ThetaDir = 'clockwise';
pax.FontSize = 12;
