Why the output of generated code has been also initialized to "M_FALSE" when set "BooleanFalseId" parameter to "M_FALSE",

I have set the CodeGen configuration of the model, "BooleanFalseId" parameter, to "M_FALSE". Then, the output of generated code has been also initialized to "M_FALSE". Why?

Hi @ChanP,

When you set the "BooleanFalseId" parameter to "M_FALSE", you are specifying that the identifier for the Boolean "false" value in the generated code should be "M_FALSE". Consequently, the generated code initializes the Boolean "false" value to "M_FALSE" to reflect this setting.

You may refer to the below MathWorks documentation link to know more about the Boolean Identifiers: https://www.mathworks.com/help/ecoder/ug/customize-boolean-and-data-type-limit-identifiers.html#:~:text=rtwtypes.h.-,Boolean%20Identifiers,-You%20can%20control

The configuration above ensures that "M_FALSE" is numerically equivalent to 0, as specified by the requirement that false must be numerically equivalent to 0 and true to 1. If no external header file is imported, the generated "rtwtypes.h" file will define these identifiers accordingly, ensuring consistency in the representation of Boolean values across the generated code.

I hope this helps!
