    %% Share Data Between Code Generated from Simulink, Stateflow, and MATLAB
% Stateflow and MATLAB Coder can fully define their data definitions, or they can
% inherit them from Simulink. Data definition capabilities include:
% 
% * Inheriting input/output data types and sizes from Simulink.
% * Parameterized data types and sizes.  That is, data type and size may be specified
%    as a function of another data's type and size, e.g., |type(y)=type(u)| and |size(y)=size(u)|.
% * Inferred output size and type from Simulink via signal attribute back propagation.
% * Parameter scoped data, which allows referencing Simulink parameters in Stateflow and
%    MATLAB.
%% Open Example Model
% Open the example model |rtwdemo_dynamicio|.

open_system('rtwdemo_dynamicio')
%% Instructions
% # Compile the model (*Simulation > Update Diagram*) and note the displayed signal types and sizes.
% # Change the data type and/or size of the Constant block and recompile the model. Note
%    that the attributes of the signals automatically adapt to the Constant block specification.
% # Generate and inspect code using the blue buttons in the model. Note that |K| is shared
%    by the Gain and sfVerticalSum block.
%% Notes
% * The data type and size of all Stateflow and MATLAB data is inherited from Simulink.
% * The Gain block and the Stateflow chart sfVerticalSum share the Simulink parameter |K|, which is
%    defined in the MATLAB workspace as a Simulink.Parameter with |SimulinkGlobal| storage
%    class (i.e., |rtP.K| in the generated code).
