    %% Plot Multiple Lines on Same Figure
% Plot multiple lines either by passing the inputs as a
% vector or by using |hold on| to successively plot on the same figure.
% If you specify |LineSpec| and Name-Value arguments, they apply to all
% lines. To set options for individual lines, use the function handles returned by |fplot3|.
% 
% Divide a figure into two subplots using |subplot|. On the first subplot,
% plot two parameterized lines using vector input. On the second
% subplot, plot the same lines using |hold on|.
