    %% Parameterized Mesh Plot
% Plot the parameterized mesh

% $$\matrix{x = r\cos(s)\sin(t) \cr y = r\sin(s)\sin(t) \cr z = r\cos(t)
% \cr {\rm where\quad} r = 8+\sin(7s+5t)}$$
% 
% for $0<s<2\pi$ and $0<t<\pi$. Make the aspect ratio of the axes equal using
% |axis equal|. See the entire mesh by making the mesh partially transparent
% using |alpha|.
