    %% Control Number of Decimals for _r_-Axis Tick Labels
% Display the _r_-axis tick labels with two decimal places. Control the
% decimal places by passing |rtickformat| a character vector of a numeric
% format that uses fixed-point notation for the conversion character and a
% precision value of 2.

theta = 0:0.01:2*pi;
rho = 50*sin(2*theta);
polarplot(theta,rho)
rtickformat('%.2f')
