%% Improve Code Readability by Generating Block Parameter Values as Macros
% When you generate efficient code by inlining the numeric values of block
% parameters (with the configuration parameter *Default parameter
% behavior*), you can configure scalar parameters to appear as macros
% instead of literal numbers. Each macro has a unique name that is based on
% the name of the corresponding block parameter.
%
% Open the example model |sldemo_fuelsys_dd_controller|.
sldemo_fuelsys_dd_controller
%%
% The model uses these configuration parameter settings:
%
% * *Default parameter behavior* set to |Inlined|.
% * *System target file* set to |ert.tlc|.
%
% Set the configuration parameter *Generate scalar inlined parameters as*
% to |Macros|.
set_param('sldemo_fuelsys_dd_controller','InlinedPrmAccess','Macros')
%%
% Generate code from the model.
rtwbuild('sldemo_fuelsys_dd_controller')
%%
% The header file |sldemo_fuelsys_dd_controller_private.h| defines several
% macros that represent inlined (nontunable) block parameters. For example,
% the macros |rtCP_DiscreteFilter_NumCoe_EL_0| and
% |rtCP_DiscreteFilter_NumCoe_EL_1| represent floating-point constants.

% block uses the macros.
