%% Create Feather Plot
% Define theta as values between -2\pi and 2\pi. Define r as a vector the same size as theta.

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)
