%% Plot Parameterized Surface % Define the parametric surface |x(s,t), y(s,t), z(s,t)| as follows. % Copyright 2015 The MathWorks, Inc. syms s t r = 2 + sin(7*s + 5*t); x = r*cos(s)*sin(t); y = r*sin(s)*sin(t); z = r*cos(t); %% % Plot the function using |ezsurf|. ezsurf(x, y, z, [0, 2*pi, 0, pi]) title('Parametric surface') %% % To create a smoother plot, increase the number of mesh points. ezsurf(x, y, z, [0, 2*pi, 0, pi], 120) title('Parametric surface with grid = 120')
