Can the constant and gain block be saved as C code variables using the Simulink coder?

Hi all,
I am working to create a library by generating C code with Simulink coder.
When I checked the generated code, it was confirmed that the Contant and Gain blocks are directly used as numbers in C code.
I would like to have the Contant and Gain blocks as variable parameters.
Is this possible? I am wondering which option should be checked if possible.
Thanks.

I I got an answer from Technical Service.
-------------------------------------------------------------------------------------------------------------------------------------------------------------
When you set Configuration Parameters > Optimization > Signals and Parameters > Default parameter behavior (see Default parameter behavior (Simulink)) to Tunable (the default when you use a GRT-based system target file such as grt.tlc), the generated code allocates memory to represent block parameters. Therefore, you can tune the block parameter values during code execution.

Hi,
You could always change your code after code generation using simulink coder. But if you want to save as variable in gain and constant block you could create a workspace variable and use that in those blocks.
Refer to the following link for more information on the workspace variables.
