%% Create a Stairstep Plot using plot Function % Evaluate two cosine functions at 50 equally spaced values between 0 and % $4\pi$ and create a stairstep plot using |plot|. % Copyright 2015 The MathWorks, Inc. %% X = linspace(0,4*pi,50)'; Y = [0.5*cos(X), 2*cos(X)]; [xb,yb] = stairs(X,Y); %% % |stairs| returns two matrices of the same size, |xb| and |yb|, but no plot. %% % Use |plot| to create the stairstep plot with |xb| and |yb|. figure plot(xb,yb)
