    %% Specify r-Axis Tick Labels for Specific Polar Axes
% Create a polar plot and assign the polar axes object to the variable
% |pax|. Ensure that |rticks| and |rticklabels| affect the polar axes you
% just created by specifying |pax| as the first input argument to the
% functions.

theta = 0:0.01:2*pi;
rho = 50*sin(2*theta);
polarplot(theta,rho)
pax = gca;

rticks(pax,[10 25 50])
rticklabels(pax,{'r = 10','r = 25','r = 50'})
