%% Create Feather Plot % Define |theta| as values between $-2\pi$ and $2\pi$. Define |r| as a vector the % same size as |theta|. % Copyright 2015 The MathWorks, Inc. theta = -pi/2:pi/16:pi/2; r = 2*ones(size(theta)); %% % Create a feather plot showing the direction of |theta|. Since |feather| % uses Cartesian coordinates, convert |theta| and |r| to Cartesian % coordinates using |pol2cart|. [u,v] = pol2cart(theta,r); feather(u,v)
