    %% Display Input Signal of Changing Size  

%% 
% At the MATLAB(R) command prompt, type <matlab:ex_timescope_varsize ex_timescope_varsize>
% to open the example model. The following Simulink(R) model appears.  
%
% <<../timescope_example2_model_var.png>>
%
%% 
% In this example, the size of the input signal to the Time Scope block
% changes as the simulation progresses. When the simulation time is less
% than 5 seconds, Time Scope plots the signal connected to the third input
% port of the Switch block, which has signal dimensions 1 by 2. After 5
% seconds, Time Scope plots the signal connected to the first input port
% of the Switch block, which has signal dimensions 1 by 3. Run your model
% to see the time domain output.

% As you can see in the figure, the third line on the display, colored red,
% appears only after 5 seconds.
