%% Axes Handles
% Specify the axes for a 3-D stem plot.
% Define vectors X, Y and Z.

X = linspace(-2,2,50);
Y = X.^3;
Z = exp(X);

% Create a figure with two subplots and return the handles to each axes, s(1) and s(2). Plot a 3-D stem plot in the lower subplot by referring to its axes handle, s(2). For comparison, plot a 2-D stem plot in the upper subplot by referring to its axes handle, s(1).

s(1) = subplot(2,1,1);
s(2) = subplot(2,1,2);  

stem(s(1),X,Z)
stem3(s(2),X,Y,Z)
